The K7RA Solar Update
SEATTLE, WA, May 12, 2006--This week saw higher geomagnetic activity and lower sunspot numbers than the previous period (our reporting week is Thursday through Wednesday). Average daily sunspot numbers declined more than 5 points to 54.3. Today, May 12, look for active geomagnetic conditions with a planetary A index predicted at 25, then declining to 12 and 10 on Saturday and Sunday. Sunspot numbers and solar flux should be a bit lower than the past week. Geophysical Institute Prague predicts active geomagnetic conditions for today, May 12, unsettled May 13, quiet to unsettled May 14, nice and quiet May 15-16, back to quiet to unsettled for May 17, and unsettled conditions on May 18. Many readers alerted us to a new long-range sunspot cycle prediction. This time it wasn't for upcoming Cycle 24, but the peak of Cycle 25, which should reach solar maximum around 2022. Think that's a long way off? It depends on your perspective, determined by the proportion a given time period represents in comparison with how long you've been around. For instance, when starting out at age 12 as WN7CSK in early 1965, looking ahead 16 years I would be 28, and the year 1981--hard to fathom at the time. The old-timers I knew then, such as Howard S. Pyle, W7OE, first on the air around the same age in 1907, would have laughed out loud at such an assessment. This spring marked 16 years since I began compiling this weekly bulletin. And 16 years from now, in mid 2022, I will turn 70, a terrifying notion, because the last 16 years went by so fast. I suspect the next 16 years to flash by shortly. Even those of us who got into ham radio at a young age can't expect to see very many solar cycles. Let's hope the soon-to-begin Cycle 24 is huge, reminiscent of the awesome Cycle 19 of the 1950s. We saw a prediction in March that the upcoming Cycle 24 could be a big one. Using the same method of indirectly observing a massive circulating current of solar plasma, a report from NASA solar physicist David Hathaway shows a stunted-looking Cycle 25. Read about it in an article by NASA's Tony Phillips. Roger Barnhill, AB8RX, of Lansing, Michigan asks: "Where can I find up-to-date info on which way Earth's magnetic field is pointing at any particular time?" You can find this on the SpaceWeather.com site. Look down the left side under "Interplanetary Magnetic Field." When Earth's magnetic field is pointing south, Earth is vulnerable to solar wind and more likely to experience greater geomagnetic activity. HS0ZFQ tipped us off to a Web page, "The short history of the Smoothed Sunspot Number." It discusses the various sources for smoothed sunspot numbers needed for propagation prediction programs using the VOACAP ("Voice of America Coverage Analysis Program") engine. One example called HamCAP is from VE3NEA, and it's free! Mike Schaffer, KA3JAW, in Florida, enjoys observing sporadic-E propagation on broadcast television. On May 11 at 1750 UTC and again at 2215-2230 UTC he observed Canal 2 on TV channel 2 coming from Nicaragua about 1100 miles away! For more information concerning propagation and an explanation of the numbers used in this bulletin see the ARRL Technical Information Service Propagation page. An archive of past bulletins is on the ARRL Web site. Sunspot numbers for May 4 through 10 were 50, 61, 69, 64, 53, 56 and 27, with a mean of 54.3. 10.7 cm flux was 91.8, 86.7, 87, 86.2, 84.7, 82.6, and 78.2, with a mean of 85.3. Estimated planetary A indices were 14, 13, 24, 19, 8, 4 and 4, with a mean of 12.3. Estimated mid-latitude A indices were 10, 8, 14, 17, 5, 2 and 4, with a mean of 8.6.

Scientist Warn of Immense Solar Storm.
Story of the Day 2 at www.stevequayle.com (Click on the big Q) In a million years,there wont be anything here.Human beings are self destructing.Like that old guy in that boat checking the oil in the Waterworld movie said,Thank God! cuhulin |

(K7RA, ARRL) dxAce Michigan USA Propagation has been crappy here lately mostly anything above 11 MHZ is dead at night except for a few ham stations you hear. I was listening today to 13, 15, 17, 21 MHZ and it was lousy even the stations I've listened to for years were horrendous. I recall that 15475 Radio Africa one was buried behind a lot of static and poor reception. I know the stations are still there but its been poor lately. Not to mention 20 meters amateur radio being lackluster especially for long distance DX. |
