Observing 'RDCS1252-29' (obsid 4198) with ACIS-I. Soft proton levels have decresed to very low levels (under 100) from recent peak. 3-day Solar-Geophysical Forecast issued Mar 20 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be moderate for the next 24 hours due to possible additional flare activity from Region 314. Conditions should decline to low levels for the second and third day as Region 314 will be behind west limb. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly active for the next 24 hours as the current activity persists. A gradual decline to unsettled levels is expected for the seconds and third days.
