[DX-NEWS] ARLP016 Propagation de K7RA
SB PROP @ ARL $ARLP016 ARLP016 Propagation de K7RA ZCZC AP16 QST de W1AW Propagation Forecast Bulletin 16 ARLP016 From Tad Cook, K7RA Seattle, WA April 23, 2010 To all radio amateurs SB PROP ARL ARLP016 ARLP016 Propagation de K7RA A Sun with no sunspots! The quiet Sun returned -- and through Thursday, April 22 there have been eight days straight with no sunspots. A new spot began to emerge on Wednesday, but it quickly faded. For the next ten days NOAA/USAF predict solar flux at 78, 78, 80, 80, 80, 78, 76, 80, 80 and 80. Solar flux values above 80 aren't predicted until May 20-23, with a value of 85, but that is too far into the future to predict accurately. They also predict the return of sunspot group 1061 on April 23-25. That sunspot group was previously visible on April 5-10. Planetary A index for April 23 through May 2 is predicted to be 8, 6, 5, 5, 5, 8, 8, 5, 5 and 5. Geophysical Institute Prague predicts quiet to unsettled conditions for April 23, then quiet April 24-26, quiet to unsettled April 27, and back to quiet for April 28-29. Carl Luetzelschwab, K9LA has a new propagation column about sunspot Cycle 24 in the current issue of WorldRadio online at http://www.worldradiomagazine.com. Carl's columns are always worthwhile, and a new issue of WorldRadio appears on the twentieth day of each month. We've seen some reports of 10 meter activity over the past couple of weeks. Julio Medina, NP3CW of Puerto Rico reports that on April 9 he saw an opening to the Pacific on 10 meters. He writes, H44MS at 2122z SSB, KH6CE Henry, ZL4IV Rick at 2159z, HR1RJF, KC5JAR from TX, and LU5FCI at 2255z. Around the start of the month he had 6 meter openings to South America. Pat Dyer, WA5IYX sent in a report generated by DX Sherlock, which automatically collects propagation data from a network of WSPR stations. WSPR stands for Weak Signal Propagation Reporter. Pat said that on April 12, 10 meters opened up to the Pacific, which is normal after a geomagnetic storm. You can go to http://www.vhfdx.net/spots/index.php to generate your own propagation snapshots, including maps. Peter Sils, KD0AA of Nixa, Missouri wrote that there was a wonderful 10 Meter opening on Wednesday, April 14 at 8:30 PM CDT. I was alerted by Mark, K0ABC via Nixa ARC email that there was a Tahiti station on. I proceeded to work FO8RZ, ZL1BYZ and VK7ZE on a NB6ZEP antenna up 30' with 100 watts. What a wonderful opening it was! Bill Alsup, N6XMW of San Francisco wrote, I read years ago that there was a correlation between how closely the planets aligned and the sunspot cycle, the idea being that the more intense the gravitational pull on the Sun, the more sunspots would appear. Evidently, they more or less align every 11 yrs. I have never seen any other reference to that concept. That was by J.H. Nelson, a forecaster at RCA who wrote about it in the 1950s. The reason you never heard of it since the 1970s (although astrologers like it) is that it didn't work, and it proved to be no better than chance at predicting anything. What Nelson worked out was a system in which certain planetary alignments were thought to put some sort of tidal influence on the Sun, and that there were more solar flares at those times, causing HF radio disruption. He kept records for many years, and worked out a system that when these alignments occurred, there was a three-day period in which these events were likely to occur. So if the alignment is on Wednesday, the disruption could occur Tuesday through Thursday. In the early 1980s the Skeptical Inquirer published an article in which they went over his records, and counted the number of occurrences per year. Then they randomly distributed the same number of dates over each calendar year, and used the three-day rule. The correlation was no worse than Nelson's predictions. So it had zero prediction value, because you could just as easily toss dice. A stopped clock is correct twice per day. Check this article at http://www.rudolfhsmit.nl/d-arti2.htm which mentions Nelson's work. It also talks about false correlations. I dug up an interesting thread on Nelson at http://www.eham.net/articles/8828, and the best comments are by N3AIU, who also is a reader of our propagation bulletin. Several people wrote in to comment about volcano ash and propagation, and this is from Tom Segalstad, LA4LN of Oslo, Norway. Some countries have allowed radio amateurs to use the 70 MHz (4 m) band. A number of contacts are being made every day on this band between radio amateurs in some European countries via meteor scatter using the K1JT digital modes JT6M and FSK441. On 14 April this year the Icelandic volcano Eyjafjallajokull started an explosive eruption, which produced a high column of volcanic ash. With westerly winds, the ash cloud was blown towards Europe in the stratosphere. In the NRAU (Nordic Radio Amateur Union) Nordic Activity Contest on 70 MHz Thursday 15 April we experienced fairly poor
