Analysis of Solar Active Regions and Activity from 27/2100Z to 28/2100Z: Solar activity was very low. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic field has been at unsettled to minor storm levels. Minor storming was observed at all latitudes as the solar wind increased to about 700 km/s due to a coronal hole high speed stream. Solar wind speed remains elevated at approximately 640 km/s. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active on 01 March due to the coronal hole high speed stream. Expect quiet to unsettled conditions on 02 - 03 March. III. Event Probabilities 01 Mar-03 Mar Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
