SB PROP @ ARRL $ARLP051 ARLP051 Propagation DE KT7H QST DE W1AW Propagation Forecast Bulletin 51 ARLP051 >From Tad Cook, KT7H Seattle, WA December 9, 1994 To All Radio Amateurs Average solar flux was exactly the same last week as the week prior. Values hovered around 80. The one day with active geomagnetic conditions was December 2 when the A index was 20 and the K index rose as high as five. The solar flux is expected to stay right around 80 for the rest of December. There may be a slight dip around mid month, but otherwise there should be little change. Geomagnetic conditions may be unsettled around December 17, and active to storm levels around December 23, remaining unsettled to active through December 29. Sunspot Numbers for December 1 through 7 were 15, 12, 11, 14, 14, 16 and 28, with a mean of 15.7. 10.7 cm flux was 79.1, 79.1, 81.8, 81.9, 80.7, 78.5 and 80.1, with a mean of 80.2. The path projection for this week is from Minneapolis to Malta. 80 meters should be open from 2130z to 0700z, and 40 meters from 2000z to 2330z and again from 0300z to 0800z. On some days 40 meters may be open through the period from 2330z to 0300z. 30 meters looks good from 1500z to 1830z and again from 0530z to 0800z. Check 20 meters from 1430z to 1800z and 17 meters from 1530z to 1700z. 15 meters might be open on some days around 1600z, but the ham bands above 21 MHz do not look promising over this path. /EX
