Solar activity was at low levels. Only a few minor C-class flares occurred during the period. One event of note, was a 12 degree filament (centered at S21E12) that erupted between 07/1643 and 1651 UTC. An associated long duration C2 x-ray flare and an optical sub flare occurred in the area of the filament's eruption. LASCO/EIT imagery has not updated sufficiently, to be able to ascertain at this time, if a Coronal Mass Ejection (CME) was created from the disappearing solar filament (DSF). Due to the central location of the DSF, an accompanying CME could very possibly be geoeffective. Two new regions were numbered: 9655 (S21E52) and 9656 (S21W13).

Solar activity is expected to be at mostly low levels. Isolated M-class events are possible.

The geomagnetic field was quiet. The greater than 10 MeV proton flux at geosynchronous orbit remained at elevated levels but below the proton event threshold of 10 pfu.

The geomagnetic field is expected to be mostly quiet to unsettled. Active conditions are possible on the second day of the forecast due to a small recurrent coronal hole and its associated high speed stream.
