ARLP024 Propagation de KT7H
There were five consecutive days recently with no sunspots at all. Solar flux over the past week stayed below 70, and averaged 10 points lower than the previous period. Geomagnetic conditions were also stormy, making conditions poor all around. The current poor conditions are caused by a recurrent coronal hole, and should last through June 3. Another expected poor period is due from June 12 through 16, with the same cause.
Solar activity is expected to stay low. Somewhat higher flux is expected by the middle of the month.
Sunspot Numbers for May 25 through 31 were 0, 0, 0, 13, 17, 13 and 12, with a mean of 7.9. 10.7 cm flux was 67.1, 66.3, 65.8, 66.6, 66.8, 67.5 and 68.9, with a mean of 67.
The current path projection is from Ohio to West Central Africa.
80 meters should be open from 0100 to 0400z, and 40 meters from 2330 to 0500. Check 30 meters from 2230 to 0545, and 20 meters from 1930 to 0200. The higher bands do not look promising given the low solar activity.
