Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: Solar activity was very low. No flares were observed over the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with a slight chance for isolated active periods on 14-15 March due to a recurring coronal hole. Quiet conditions are expected on 16 March. III. Event Probabilities 14 Mar-16 Mar Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
