Average solar flux for the past week was nearly nine points lower compared to the week before, and every day the flux was lower than the average for the previous ninety days. Conditions were disturbed on September 3 and 4 due to a coronal hole. Recurring coronal hole activity should produce more severe disturbances in a couple of days, around September 12 and 13. This could cause some disruption during the Worked All Europe DX Contest over the weekend. Next watch for a slight increase in solar flux, peaking near 95 around September 21 through 24. Flux levels should drop to around where they are now after the beginning of October. Sunspot Numbers from September 2 through 8 were 33, 36, 42, 33, 29, 14 and 27, with a mean of 30.6. 10.7 cm flux was 81.1, 79.6, 79.2, 80, 78.9, 78.4 and 79.1, with a mean of 79.5. The projection for this week is from Arlington Heights, Illinois to Germany. 80 meters should be open from 2230 to 0630z, peaking from 0030 to 0430z. 40 meters should be open from 2130 to 0630z, with the best times from 2330 to 0530z. 30 meters should be good from 1700 to 2330z, and one a some days on into the local USA evening. 20 meters looks good from 1330 to 2200z, and best from 1500 to 2030z. 17 meters may be open on some days beginning at 1330z and more often starting around 1630 until around 2100 or 2300z. 15 meters does not look too promising, but on a few days per month it may be open from 1630 to 2130z. 12 meters may be open on some days from 1830 to 2000z. 10 meters does not show much promise this coming week over this path.
