Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 303 Issued at 2200Z on 29 Oct 2012
IA. Analysis of Solar Active Regions and Activity from 28/2100Z
to 29/2100Z: Solar activity was very low. The largest and only
event of the period was a B6 flare at 29/0302Z from Region 1596
(N05W79). Regions 1601 (S10E11) and 1602 (S17E65) were numbered
today. No Earth-directed CMEs were detected during the reporting
period.
IB. Solar Activity Forecast: Solar activity is expected to be low
with a slight chance for M-class flares.
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet on day 1 (30 October). Quiet conditions are
expected again on day 2 (31 October) until the arrival of the CMEs
from 27/28 October, when there is a chance for active conditions
late in the period. Active conditions are again likely with a
chance for minor storm conditions on day 3 (01 November).
