SDF Number 057 Issued at 2200Z on 26 Feb 2001

IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z

Solar activity was low. An optically uncorrelated C1 x-ray flare occurred at 26/0741 UTC. The probable source for this event was observed by SOHO/LASCO from behind the west limb.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was quiet to unsettled. An isolated period of active conditions occurred at 26/1800 UTC. A slight proton enhancement was observed which was probably associated with the event which occurred behind the limb earlier today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled for the forecast period.
