SB PROP ARL ARLP034 ARLP034 Propagation de K7RA Thanks to Carl Luetzelschwab, K9LA for writing the excellent bulletin last week. If you missed it, be sure to check <a href="http://www.arrl.org/w1aw/prop/2008-arlp033.html">http://www.arrl.org/w1aw/prop/2008-arlp033.html</a> because it is full of useful information. Our sun is still not producing any sunspots. As mentioned in previous bulletins, the peak of the last cycle was a double peak, so perhaps we are in the midst of an extended bottom. Roger Lapthorn, G3XBM reported six-meter observations. ''Following on from comments in the Aug 8th propagation bulletin, I'd like to mention Aug 6th when, here in the UK on just a small VHF collinear, I heard both D4C and K1TOL on 6m CW. The Cape Verde station was working a string of EU stations and peaked at 539 with me. Lefty, K1TOL (who I worked last year on 6m with just 2.5W!) was 569 and a solid signal for 15 minutes. A little later I was able to work N2MM on 10m SSB with just 10W and a halo antenna. My summary is that 6m (and 10m) truly is a magic band if one can hear such DX on such a simple antenna ...and at sunspot minimum. Last year's experience of working K1TOL confirmed that it is possible to work such DX too with a bit of luck and decent sporadic-E''. The following is from Scott Bidstrup, WA7UZO, and is so interesting I thought I should include it in its entirety. ''I live in Costa Rica (EK70rc), and at this low latitude, propagation is significantly different than in the States. I have been having a lot of fun exploring those differences, and recently downloaded and installed BeaconSee to watch propagation from the NCDXF/IARU beacon network. And I have noticed something you might find to be quite interesting. While monitoring the NOAA space weather page at <a href="http://www.swpc.noaa.gov/SWN/index.html">http://www.swpc.noaa.gov/SWN/index.html</a> I discovered that when a boundary crossing occurs, there seems to be a mode switch in the propagation I see here in Costa Rica. If the Bz component is strongly positive, on 20m. and 15m., I see fairly strong signals from the 4U1UN beacon in New York, and moderately strong signals from the OA4B beacon in Peru. I can also see a weak signal from W6WX and occasionally KH6WO, and in the early morning from the ZS6 and 5Z4 beacons as well. When a boundary crossing occurs, it's like someone throws a switch - over three or four minutes, 4U1UN fades, the W6 and KH6 beacons disappear, and OA4B booms in. The bands will get somewhat noisy until the Bz becomes settled in the decidedly negative, at which point the noise will subside and the OA4B beacon will become so strong I can even hear it in the 100mw mode. But I can hear practically nothing else on the band, and see the 4U1UN beacon only very weakly. When the bands are in this mode, 10m. is open to South America, but only to stations in an arc across the middle of the continent from Santiago to a range from Buenos Aires to Sao Paulo - no other stations need apply. This bimodality seems to be inversely correlated to solar wind speed. the higher the wind speed, the smaller the effect. It seems to be positively correlated with the proton density - the stronger the proton flux, the stronger the signals from South America''.

Please see August QST, page 74 and the ARRL and WA7BNM Contest Web Sites for details. ------------------- As mentioned in last week's Bulletin, Carl Luetzelschwab, K9LA, is filling in for your regular reporter Tad Cook, K7RA. For the reporting period August 1 through August 7, solar activity was at very low levels and the geomagnetic field was at quiet levels. Solar activity is expected to be very low for the next several days. As for geomagnetic field activity, the Australian Space Forecast Centre issued a geomagnetic disturbance warning on August 6 for quiet to unsettled and then unsettled to active conditions (with possible minor storm periods) on August 8 and August 9, respectively. Other than a new-cycle magnetic dipole on August 3 that didn't turn into a sunspot region, the Sun was again blank for the entire reporting period. Kind of sounds like a recording, doesn't it? A good summary is: Here we sit at solar min Wondering when Cycle 24 will begin It seems like we've been at solar minimum forever. In fact, there have been several news releases hinting that this solar minimum period between Cycle 23 and 24 is unusual. The analysis of recent spotless days compared to historical spotless days (see science.nasa.gov/headlines/y2008/11jul_solarcycleupdate.htm) led Dr. David Hathaway (NASA solar physicist) to conclude that nothing is unusual about this solar minimum period. Another way to look at solar minimum is to look at the duration when the smoothed sunspot number is below 20. Historically this duration has ranged from a short 17 months to a long 96 months, with an average of 37 months. Cycle 23 descended below 20 in February 2006, and Cycle 24 is predicted to ascend above 20 in early 2009. That's around 36 months, so everything appears to be pretty normal so far and agrees with Dr. Hathaway's conclusion. We'll just have to be patient until Cycle 24 starts ramping up. The good news is that we have seen three sunspot regions tied to Cycle 24 (January 4, April 13, and May 5), so it's coming. What can you do around solar minimum? One activity would be to get on the low bands for the Fall/Winter season - the low bands should be very good. Another activity would be to take advantage of summer sporadic E (and in December, too, but it's not as prevalent). For example, last weekend provided some excellent 6 Meter propagation. And participants (your author included) in the CW running of the North American QSO Party (sponsored by the National Contest Journal) enjoyed 10 Meter and 15 Meter sporadic E openings (which likely happens a lot more than we think - a dead band may not be dead, just unoccupied). And since mid latitude sporadic E is not tied to sunspots, we can have fun throughout an entire solar cycle. Speaking of sporadic E, last week's Bulletin reported N4KZ working EA8/DL6FAW on 6m on both CW and SSB. This brought a reply from Norbert Scherer, DL6FAW. Norbert reports that he's been operating on 2m for many years, but his 6m activity is relatively new. Since 2006 he has been running 100W to a simple 5-element Yagi when in Spain. Norbert continues: ''In the first weeks I only heard North America in the middle of the day. I never expected any opening after midnight local time. But by carefully monitoring the beacons I was surprised to hear, for example, WZ8D/B late in the evening. Sometimes I started to call CQ and there was no reply at all. The following day, when I heard the beacon again and nothing else, there were ten people calling at the same time. Tim, KY5R, told me last week that I was the only signal on the band he could hear. I hope there will be more good propagation to NA in the coming weeks, although the sunspot number is Zero! I checked out some websites listing solar activity, sunspot number, K-index, solar winds, etc. for July 2008. But I couldn't find any correlation between the data provided there and my log.'' DL6FAW's attempt to correlate 6m Es to sunspots came out as expected - as stated earlier, there doesn't appear to be any tie between where we are in a sunspot cycle and the occurrence of mid latitude sporadic E. Finally, in last week's Bulletin Jim Henderson, KF7E, provided some good observations and comments about the day-to-day variability of the ionosphere. A good supporting example of his observations is the F2 region MUF over the Millstone Hill ionosonde (in Massachusetts), assuming it's the mid point of a 3000 km hop. In July, when the solar flux was for all intents and purposes constant, the 3000 km MUF varied from a low of 8.9 MHz to a high of 19.6 MHz. KF7E's comments, along with the Millstone Hill data, are in agreement with ionospheric studies showing that although solar radiation is the instigator of the ionization process, two other factors appear to be more significant in determining what the F2 region ionosphere is doing right now. These two factors are geomagnetic field activity and events in the lower atmosphere coupling up to the ionosphere. What does all that mean? It simply means plugging the daily solar flux into your favorite propagation prediction program really doesn't tell you what the ionosphere is doing today. This day-to-day variability is the reason our prediction programs were designed to be statistical over a month's time frame. We do not have daily predictions, and the developers never intended that they be daily predictions as they were aware of the unpredictability of the day-to-day variation of the ionosphere. Perhaps some day we'll figure all this out, but for now the best way to tell if one of the higher bands is open is to listen to the NCDXF/IARU beacons (<a href="http://www.ncdxf.org/beacons.html">www.ncdxf.org/beacons.html</a>).

Sunspot numbers for those days were 11, 12 and 11. This brings us to our practice of presenting the average daily sunspot number for the past three months, then comparing it with a monthly 3-month moving average for the past couple of years. There were 92 days in May, June and July, and 70 out of those 92 days had no sunspots. This brings us back toward the low of 3 from last fall, centered on October. The average daily sunspot number for the last three months, centered on June, was just 3.7. Jun 06 28.9 Jul 06 23.3 Aug 06 23.5 Sep 06 21.2 Oct 06 24.1 Nov 06 23.1 Dec 06 27.3 Jan 07 22.7 Feb 07 18.5 Mar 07 11.2 Apr 07 12.2 May 07 15.8 Jun 07 18.7 Jul 07 15.4 Aug 07 10.2 Sep 07 5.4 Oct 07 3 Nov 07 6.9 Dec 07 8.1 Jan 08 8.5 Feb 08 8.4 Mar 08 8.4 Apr 08 8.9 May 08 5 Jun 08 3.7 The outlook from the US Air Force Space Weather operations for many weeks now has shown a predicted solar flux of 66, and their prediction from July 31 shows the same, for the next 45 days. This tells me that there isn't any period where we might expect more sunspot activity, or at least no way to foresee it. They predict the next geomagnetic activity of any note for August 10, with a planetary A index of 20. They predict a planetary A index of 8 for August 1, then 5 for August 2-6, then 8 again on August 7. Geophysical Institute Prague echoes that prediction with quiet to unsettled conditions for August 1 and 7, and quiet conditions August 2-6. In response to WD4ELG's comments in ARLP031, Jim Henderson, KF7E of Queen Creek, Arizona has some interesting observations. Jim writes, ''During these spotless and near-minimum flux conditions, I have seen the extreme divergence of the day-to-day propagation paths as a function of the traditional flux numbers. Allowing for seasonal trends, the differences in direction and quality of openings on a given band from day-to-day where the flux and A and K indices remain nearly unchanged for days, the openings generally show much more relationship to the intensity of the solar wind''. ''From here, the patterns of propagation, under the weak stimulation of near minimum flux, show much more pronounced linking to the dynamic wind speed and composition than to simple 2800 MHz flux measurements''. ''I believe without the positive contribution of the 'ionospheric bias' provided by even a low flux, say 80-85, even a small increase in solar wind has a profound effect on the daily paths''. ''Put another way, the good/bad effects upon propagation from minor solar wind changes (not associated with flares and CMEs) are much more observable when the flux is hovering under 68 or so than when it is higher. At that time, we feel the big effects from the major storms. But it is interesting to note the nuances of propagation (say, by observing the NCDXF HF beacons daily) during a quiescent sun''. Thanks, Jim. Maurice Picard, W6FQS of Chico, California wrote: ''I noticed a forecast on a propagation website (<a href="http://dx.qsl.net/propagation/index.html">http://dx.qsl.net/propagation/index.html</a>) that the geomagnetic field would be unsettled due to a solar boundary crossing. I don't recall seeing reference to this phenomena in any previous forecasts. What is this boundary crossing?''

Another multi-hop sporadic E report from six meters, and this was just last evening. Dave Greer, N4KZ of Frankfort, Kentucky (EM78ne) reports that beginning at 2322z on July 31, on 6 meter CW he worked EA8/DL6FAW (Canary Islands) with good signals both ways. At 2325z he worked EA8AK on CW, and at 0026z on August 1 he worked EA8/DL6FAW on SSB. Dave reports that both stations made many U.S. contacts, but also called CQ many times with no takers. He thinks this is a good example of distant six meter signals propagating to very specific areas, but not others. For instance, he saw that EA6SX in the Balearic Islands was spotted on 50.105 MHz over several hours, but Dave never heard him. He also made Canary Island contacts in summer 2006 and 2007, again working stations in pairs, but earlier in the season and earlier in the day. On June 18, 2006 he worked them around 1300z, and on July 15, 2007 around 2200z. For six years his station has been on a hilltop (on Skyview Drive.) with a very steep slope toward the East and Northeast. He notes that NW Africa is a real sweet spot for him on HF, with incredibly strong signals to and from EA8, D4, CN and CT3. This seems to be true on 6 meters as well. He runs 100 watts into a 4 element Yagi at 60 feet. His best 6 meter DX ever was in November 2001 when he worked KH2GU in Guam, using an 80 meter horizontal loop antenna at a previous QTH. Bill Reichert, N9HH of Troy, Illinois reports 6 meter propagation from earlier in the month. On July 9, at 2342z while mobile from EM58br he worked CT1HZE (Portugal, IM57nh) on 50.084 MHz using a base-loaded quarter wave whip antenna. A few days earlier around 1500z, CU2JT (Azores) called him, but QRM from the East Coast prevented him from completing the contact. This was while Bill was mobile in Collinsville, IL.

This group was number 1000, and lasted from July 18-20. No sign of cycle 24 in recent memory, just a couple of false starts. The autumnal equinox, the beginning of the fall season, is less than 60 days from now. I would like to suppose that cycle 24 will be in full swing by then, but we have no way of knowing. We are still getting regular reports from readers about the continued sporadic-E activity on six and ten meters. Going back a few weeks, Mark Lunday, WD4ELG of Hillsborough, North Carolina commented ''Amazing the stuff that happens at the sunspot lulls. Actually gives calmer conditions under which to observe phenomenon like gray line prop without the geomag disturbances''. That's true, and I can recall a couple of years when there was a fair amount of sunspot activity, but month after month we witnessed severe geomagnetic storms, making HF bands nearly useless, especially at higher latitudes. Back on July 7 at 0210z Mark accidentally switched to 12 meters and heard FO5RH (French Polynesia) calling CQ on CW. This was 90 minutes after Mark's local sunset. They exchanged S5 signal reports. Two days later on July 9 at 2335z, George Pituras, W8KQE of North Olmsted, Ohio (EN91) worked CT9HZE (Portugal) on 6 meters CW, when George was running 100 watts into an omnidirectional loop antenna. The next day he worked Utah on six, completing 48 states worked using the same loop. He hopes someday to confirm Alaska and Hawaii on six. He signs his email, ''Six meters forever!'' Doug Phillips, W7RDP of Sammamish, Washington reports that on July 12 he and a group known as PNW QRP used the call K7S for an annual outing to the Bowman Bay area of Deception Pass State Park on Fidalgo Island. (48.416 deg N, 122.65 deg W, see <a href="http://tinyurl.com/5m23qg">http://tinyurl.com/5m23qg</a>). In addition to HF, Rod Johnson, WE7X ran 3 watts on 6 meter CW and SSB into a halo antenna 15 feet above his picnic table, and worked several Southern California stations in the Los Angeles and East Mojave Desert area. Jim Henderson, KF7E of Queen Creek, Arizona sends us some provocative observations regarding the double solar cycle peaks and possible double minima, mentioned by W7TJ in ARLP029. Jim writes, ''The double peak was prominent on the last two cycle maxima. Last minimum showed slight double as well. But I have stated since about mid-2005 that the coming cycle will start after a protracted, double minimum (as in a dip, slight but obvious increase, then dip). (Here he references <a href="http://tinyurl.com/557up2">http://tinyurl.com/557up2</a>) ''Of interest to me (besides the admonition that this minimum is not a record low) is the possible support of Mausumi Dikpati, et al's, forecast that this cycle will start late and be ''30-50% more intense' that is revealed in the plots for the 1933 minimum at the end of this piece. ''While we need 200+ days of spotless sun to equal 1933, a comparison of the peak of Cycle 16 (approx 80) to that of Cycle 17 (approx 120) shows that it was almost exactly 50% higher. ''Protracted low, followed by a bigger maximum. ''A bit of good news? ''It doesn't prove anything, but I am encouraged to continue placing my bet on Ms Dikpati.... ''If I am wrong about Dikpati's forecast and we go into an extended period of low cycles, I will be selling my 10/12/15m antennas and installing a 160m Yagi. :-)'' (Dikpati is reference to a 2006 prediction for a large cycle 24. See ARLP010 from 2006 at <a href="http://www.arrl.org/w1aw/prop/2006-arlp010.html">http://www.arrl.org/w1aw/prop/2006-arlp010.html</a>). Mark Bell, K3MSB from Airville, Pennsylvania writes: ''Just read Jeff Hartley's, N8II, comments about the IARU radiosport contest in ARLP030. For me, the biggest surprise was working 5B4AII (1530Z) and TA3D (1635Z) on 10 CW from PA !! They were not strong, and didn't last too long, but I got 'em. As Jeff said, the HQ stations were beacons on 10M!!'' Regarding six meters on June 22, Ed Oswald, W3DUB of Sinking Spring, Pennsylvania wrote: ''Probably not the first mail you got about six meters today but what a morning/afternoon here in FN10. 6 was open today here from the time I first got on the radio around 1600z to right around 2000z, first opening north/south with lots of stations heard here and worked from Alabama, Georgia, North Carolina, and Tennessee (W3GQ, K4LF, KM4QQ, K4AAK). Stations were booming in S9+ and the band seemed pretty packed. Around 1830z or so the band started going east/west with Minnesota, Illinois, Iowa, and Wisconsin coming in, with K9ZVZ, N2BJ, N0VZJ, and N0JJQ worked''. ''Have to say the highlight of my day was the contact with KP4A around 2000z on 50.110. That was my first ''DX'' on 6m. Altogether a dozen contacts over four hours and 11 grids. Being new here, those 11 were all new so I'm pretty happy!'' ''Not too shabby for 100 watts using an 80-10 vertical tuned for 6 (if I say so myself)!'' Several readers sent stories from Science Magazine (<a href="http://tinyurl.com/5kzphl">http://tinyurl.com/5kzphl</a>) and the Baltimore Sun (<a href="http://tinyurl.com/6nhvn6">http://tinyurl.com/6nhvn6</a>) that have nothing to do with propagation, but are interesting pieces on solar physics. For the next week, there are no predictions indicating more sunspots. Predicted planetary A index for the near future is 5, with a slight increase to 8 on August 1, and a large increase to 20 on August 8. Geophysical Institute Prague predicts quiet geomagnetic conditions through the end of the month, except July 27, which is quiet to unsettled.

NNNN /EX --------------------------------------------------------------------------------------------------------------------- SB PROP ARL ARLP030 ARLP030 Propagation de K7RA If today is like yesterday and the day before that, it will be the twenty-sixth consecutive day with no sunspots. Think this is bad? At the last solar minimum there were only four days showing any sunspots between September 5 and October 24, 2006. Chuck Shinn, W7MAP of Coppell, Texas sent in an interesting observation comparing the current solar minimum to the one between cycles 18 and 19. Cycle 19 was the biggest sunspot cycle on record, and peaked around October 1957 to April 1958. Chuck observed that there was a long period of little solar activity in 1953 and 1954. He used a table of smoothed sunspot numbers at <a href="http://tinyurl.com/5ujuak">http://tinyurl.com/5ujuak</a> and noted that from December 1953 through most of 1954 the smoothed sunspot number was less than seven. Each monthly smoothed number in this table represents an average of monthly averages, I believe for 13 months, six months prior and six months following. That's why December 2007 is the last value shown in this table, because to calculate the January 2008 number, you need to know the average of daily sunspot numbers for all of the current month, July 2008. Looking at it this way, against the 1954 minimum, the current lack of activity does not seem unusual, and the lack of 1954 sunspots didn't indicate that cycle 19 would be below average. The minimum during that period was 2.4 in April, 1954. Between cycles 19 and 20, the lowest value was 7.2 in June 1964. From cycle 20 to 21, March 1976 at 11.1 was lowest, and from cycle 21 to 22 it was September 1986 at 10. The last minimum was 8 in May and August 1996. This puts the current minimum in an interesting perspective. The current minimum is quite low, but it hasn't yet lasted as long or gone as low as the minimum preceding the largest sunspot cycle in recorded history. None of this, of course, can predict the size or length of the upcoming cycle 24. The August 2008 issue of Scientific American has an interesting article concerning solar and geomagnetic activity titled ''Bracing for a Solar Superstorm''. It begins with a narrative describing a huge space weather event on August 28, 1859, one hundred years prior to twentieth century's cycle 19. This was the fiercest ever recorded, and resulted in shutdown of telegraph traffic and aurora observed in the Caribbean. The article says a storm of this magnitude comes along every 500 years or so, but reconstructs events and imagines the impact on current technology infrastructure. There are wonderful graphics and numerous sidebars. Included are some web links I wasn't previously aware of, such as <a href="http://solarstorms.org">http://solarstorms.org</a>. Within that site at <a href="http://solarstorms.org/SRefStorms.html">http://solarstorms.org/SRefStorms.html</a> is a history of great solar events, a short primer at <a href="http://solarstorms.org/SPrimer.html">http://solarstorms.org/SPrimer.html</a>, and at <a href="http://solarstorms.org/S23rdCycle.html">http://solarstorms.org/S23rdCycle.html</a> downloadable PDFs of the book, ''The 23rd Cycle: Learning to live with a stormy star''. Jeff Hartley, N8II of Shepherdstown, West Virginia sent a report on more multi-hop sporadic-e activity, this time in the IARU contest last weekend. Jeff wrote, ''Condx would have been dreadful with a high K index (peaked at 5) if not for the multi-hop sporadic E during the IARU contest. I made about 20 QSO's on 10 running QRP and was late getting there. There were Europeans/north Africans with good signals on 10 from around 1530-19Z and again weaker from 2330 or earlier thru past 24Z. ''The HQ stations were like beacons (TM0HQ, 9A0HQ, S50HQ, GB7HQ, OL4HQ, EH8U) operating whenever the bands were open. I couldn't get thru to TM0HQ on 10M phone despite a loud S7-8 signal, but did get them easily on CW. All together about 10 Eu Q's were made and a couple with SA on 10M. 15M was open to all of EU except most of Scandinavia at its best and RU1A had a good but unworkable signal with my QRP. Best surprise was easily working ZD8Z on 20M who usually enjoys huge pile-ups. ''2nd best was getting thru to OL4HQ on 75M SSB thru the QRN. 15 was open well again in the last hour at 1100z. ''There was some action on 6M into EU from my area into CT and EA, but I was too busy with the contest.'' Last week's bulletin should have reported on the upcoming weekend geomagnetic activity. For this week, geomagnetic conditions should be mild in the beginning, increasing later. Predicted planetary A index for July 18-24 is 8, 5, 5, 5, 10, 15 and 12. Geophysical Institute Prague predicts quiet conditions for July 18, quiet to unsettled July 19-20, quiet again on July 21, and unsettled July 22-24.
