SB PROP @ ARL $ARLP033 ARLP033 Propagation de KT7H ZCZC AP47 QST de W1AW Propagation Forecast Bulletin 33 ARLP033 >From Tad Cook, KT7H Seattle, WA August 12, 1994 To all radio amateurs SB PROP ARL ARLP033 ARLP033 Propagation de KT7H Solar activity is still low. Don't expect much improvement over the next few years. We can expect a slight improvement in the short term over the solar flux values in the mid seventies that we have had lately. Around August 21 through 24 the flux is expected to climb up to around 90. Recently geomagnetic disturbances have been low, but currently we are experiencing slightly disturbed conditions from a recurring coronal hole. This may continue for a few more days. Sunspot Numbers from August 4 through 10 were 21, 27, 29, 18, 18, 18 and 33, with a mean of 23.4. 10.7 cm flux was 75.2, 75.7, 75.3, 75.8, 73.8, 73.5 and 77.6, with a mean of 75.3. The path projection for this week is from the center of the United States to Central Europe. 80 meters should be open from 0200z to 0430z, and 40 meters from 0030z to 0530z. 30 meters looks good from 0500z to 0700z, and again from 2230z to 0130z. 20 meters should be open most days from 1830z to 2330z, with the best time around 2130z or 2200z. The bands above 20 meters do not look good at this time. NNNN /EX
