Apr 10 To: info-hams@ucsd.edu Dateline: Madison Wisconsin The Madison Area Hamfest is an excellent swapfest drawing hams from several states. It's held each spring at the Dane County Expo Center in its Forum Building. It's $5 at the door with doors opening at 8:00 am. For more information you can contact Jim Waldorf KB9AQQ @ 608.249.7579 It is sponsored by the Madison Area Repeater Assoc. Even if you're going to Dayton this is one of the best in the Midwest!

Only weak B-class x-ray and sweep activity was reported this period, all before 02/1300Z. For the first time since 22 Sep 93, the disk is spotless. Of the two spotted regions reported yesterday, Rgn 7696 rotated off the disk and Rgn 7698 (S14W36) lost its spots. Solar activity forecast: solar activity is expected to be very low. The geomagnetic field has been at mostly quiet to unsettled levels until 02/0900Z when the field experienced active to minor storm levels. A favorably positioned recurrent coronal hole is believed to be responsible for activity increases. Geophysical activity forecast: the geomagnetic field is expected to remain at mostly active to minor storm levels at middle latitudes and minor to major storm levels at higher latitudes. Isolated periods of severe storm conditions can also be expected. Based on recurrence, these conditions are forecast for the entire period and are expected to persist through at least 9 April.

Middle Latitudes Active 30/30/30 Minor Storm 35/40/40 Major-Severe Storm 25/25/25 B. High Latitudes Active 30/30/30 Minor Storm 40/40/40 Major-Severe Storm 30/30/30 HF propagation conditions were near-normal until the latter part of the UTC day when levels of auroral and geomagnetic activity increased to storm levels. This produced below-normal propagation for transpolar and especially for transauroral circuits. Conditions will continue to deteriorate, affecting the middle latitudes over the next several days. Major to severe geomagnetic storming and strong levels of auroral activity could give frequent periods of useless propagation over the high and polar latitude regions, with poor to occasionally very poor propagation over many middle latitude regions. Conditions are not expected to improve during the next week. COPIES OF JOINT USAF/NOAA SESC SOLAR GEOPHYSICAL REPORTS ======================================================== REGIONS WITH SUNSPOTS.

The disk remained spotless for the second day in a row. Solar activity forecast: solar activity is expected to remain at very low levels. At middle latitudes, the geomagnetic field has been at mostly active to minor storm levels with isolated periods of major to severe storm levels observed. High latitudes experienced mostly minor to major storm levels with some isolated periods of severe storm conditions. The storm conditions are believed to be a result of a favorably positioned recurrent coronal hole. The greater than 2 MeV electron flux reached high levels at 03/1845Z. (STD: Overall electron fluence levels were generally at moderate levels.) Geophysical activity forecast: the geomagnetic field is expected to remain at mostly active to minor storm levels at middle latitudes and active to major storm levels at high latitudes. Isolated periods of major storm levels at mid lats and severe storm levels at high lats can be expected. Based on recurrence, these conditions are forecast for the entire period and can be expected to persist through 9 April.

High Latitudes Active 30/30/30 Minor Storm 40/40/40 Major-Severe Storm 30/30/30 HF propagation conditions became strongly disturbed over the high and polar latitude paths with the arrival of the anticipated geomagnetic storm. Strong fading and absorption along with heavy multipathing has degraded most transpolar and transauroral circuits. Conditions were generally extremely poor to unusable with frequent radio-blackout conditions for high and polar latitude signal circuits. Middle latitude paths have also been moderately affected with well below normal signal quality, reduced MUFs and strong levels of fading and absorption. Low latitudes observed near-normal propagation with occasional minor signal degradation bringing overall signal qualities within the good to fair range. Conditions will continue strongly degraded over the next 24 to 72 hours with very little improvements (particularly on the upper middle to polar latitude paths) expected over the next week.
