The two currently visible sunspot groups are further declining. A small active region is near the southeast limb. No C-class flares or earth- directed coronal mass ejections (CMEs) were observed.

Quiet flaring conditions are expected, with an increasing chance on an isolated C-class flare with the possible return of old active regions over the east limb during the next few days.

The glancing blow from the 19 July CME resulted in somewhat intenser geomagnetic conditions than expected. Wind speed gradually picked up from about 340 km/s around 15:30UT to a maximum near 480 km/s around 06:00UT. Bz was mostly negative from 21:00-23:00UT at -9 nT, and especially from 03:00-07:00UT at a constant -11 nT. Minor storm conditions were recorded in Dourbes at 08:00UT, and globally during the 06:00-09:00UT interval. Starting shortly after 08:00UT, the solar wind speed started to increase again from about 400 km/s to its current values between 450 and 500 km/s, while Bz is fluctuating between -6 and +6 nT.

Mostly quiet to active geomagnetic conditions are expected, with a chance on a minor storming period in response to the high speed stream from the positive CH on the northern solar hemisphere.
