IA. Analysis of Solar Active Regions and Activity from 22/2100Z
to 23/2100Z: Solar activity was very low. No flares were observed
during the past 24 hours. The solar disk remains spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z:
The geomagnetic field was at quiet to unsettled conditions. A
continued influence of the recurrent coronal hole high speed stream
is reflected in ACE solar wind measurements. Solar wind velocities
gradually increased from around 420 km/s to a peak of 487 km/s with
interplanetary Bz fluctuations from +5 to -5 nT.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be predominately quiet for the next three days (24-26
February).
