IA. Analysis of Solar Active Regions and Activity from 24/2100Z
to 25/2100Z: Solar Activity was very low. No flares occurred during
the past 24 hours.
IB. Solar Activity Forecast: Solar Activity is expected to be very
low.
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was mostly quiet with two isolated unsettled
periods, 25/0000-0600Z. A secondary solar wind data source,
SOHO/MTOF, indicated the earth is currently in a high speed stream,
preceded by a co-rotating interaction region detected by the ACE
spacecraft early yesterday. Wind speeds, as measured by SOHO/MTOF,
averaged 430-470 km/sec during the past 24 hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled on day one (26 Nov) based on
recurrence. Quiet conditions are expected to return on days two and
three (27-28 Nov).
