Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity was very low. No flares were observed during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for an isolated C-flare during the next three days (6-8 February). IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field was predominantly quiet during the past 24 hours. A solar sector boundary crossing was noted today in the solar wind data reported by ACE. The greater than 2 MeV electron flux reached high levels during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the next three days (6-8 February) III.
