SDF Number 283 Issued at 2200Z on 10 Oct 2010

IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z

Solar activity was very low. Region 1112 (S18E54) produced a few moderate level B-class flares during the period.
IB. Solar Activity Forecast
Solar activity is expected to be at predominately very low levels with a slight chance for C-class activity for the next three days (11 - 13 October).
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled with isolated active levels at high latitudes on days one and two (11 - 12 October). This activity is due to a small, geoeffective coronal hole coupled with glancing blow effects from the 06 October full-halo CME. Day three (13 October) will see a return to mostly quiet conditions.
