IA. Analysis of Solar Active Regions and Activity from 26/2100Z
to 27/2100Z: Solar activity was very low.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet to unsettled levels with isolated active
conditions for 28 October. Predominately unsettled levels with
isolated active conditions, and possible isolated minor storm
conditions at high latitudes, are expected for 29-30 October.
Increased activity is due to a recurrent coronal hole high speed
stream becoming geoeffective.
