Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 333 Issued at 2200Z on 29 Nov 2010
IA. Analysis of Solar Active Regions and Activity from 28/2100Z
to 29/2100Z: Solar activity was very low during the past 24 hours.
Region 1130 (N13W14) has grown slightly and is a Dai-Beta type spot
group. A filament disappeared near N19W10. The eruption was
visible on SDO/AIA 193 at approximately 29/0100 UTC.
IB. Solar Activity Forecast: Solar activity is expected to be very
low with a chance for isolated C-class events for the next three
days (30 Nov-02 Dec).
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field was predominately quiet during the past 24
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be mostly quiet to unsettled with a slight chance for
isolated active periods for days one and two (30 Nov-01 Dec) due to
a recurrent coronal hole high-speed stream. Mostly quiet conditions
are expected for day three (02 Dec) as the effects from the coronal
hole high-speed stream subside.
