IA. Analysis of Solar Active Regions and Activity from 28/2100Z to 01/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 1 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low on days one, two, and three (02 Mar, 03 Mar, 04 Mar).

IIA. Geophysical Activity Summary 28/2100Z to 01/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 436 km/s at 01/0006Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 872 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (02 Mar, 03 Mar, 04 Mar).
