Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 239 Issued at 2200Z on 26 Aug 2012
IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity was low. The largest flare in the past
24 hours was a C1 at 1817Z from a region just around the east limb.
No CMEs observed in the past 24 hours are expected to be
geoeffective.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low with a slight chance for moderate activity.
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
Geomagnetic activity was at quiet to unsettled levels with an
isolated period of active and major storm levels at high latitudes.
IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be at quiet to unsettled levels with a slight chance for
active conditions. A slight chance exists for high latitudes to
reach major storm levels on 27 August, increasing to a chance on 28
- 29 August. Increased activity is due to coronal hole high speed
stream effects.
