Analysis of Solar Active Regions and Activity from 25/2100Z to 26/2100Z: Solar activity was very low. No significant activity has been observed during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic field has been quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (27 February - 01 March). Isolated active periods are possible on 27 February due to a recurrent coronal hole high speed stream. III.
