Very low activity level. Flat GOES flux except for a long-duration A class flare June 29. AR 11022 disappeared on the west limb June 29 and AR 11023 is still visible.A new region has rotated onto the disk on the eastern limb. The position of the new region on 30-Jun-2009 is S25E62 ( -757", -419" ).
SSR goes to 0% at the end of the daily pass set (max 25%). Decimation was normal/active for the week.
Detector G8 has been lowered by 6 steps and detector G1 by 4 steps this morning as requested by David Smith. The exact times for these operations are
