Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 304 Issued at 2200Z on 30 Oct 2012
IA. Analysis of Solar Active Regions and Activity from 29/2100Z
to 30/2100Z: Solar activity was very low. Region 1598 (S11W51)
produced a B8 flare at 0137Z. A filament eruption occurred from
0640Z to 0855Z near S32E07 with a heliographic extent of 24 degrees.
IB. Solar Activity Forecast: Solar activity is expected to be very
low with a chance for low level activity.
IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z:
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be mostly quiet on day 1 (31 October), increasing to a
chance for active levels with the arrival of the 27 and 28 October
CMEs late in the day. Unsettled to active with a chance for minor
storm levels are expected on day 2 (1 November) from CME effects.
On day 3 (2 November) conditions are expected to decline to quiet to
unsettled with a chance for active as CME effects subside.
