Based on this recent data Propulsion is recommending a change in the MP guideline for dwelling at a warm attitude from 7 hours to 10 hours. This stricter constraint will be brought to the FDB for approval. Radiation: - The sun remains extremely quiet and the radiation environment is quiet as well, with the exception of slight elevation due to a solar stream - Solar Activity Forecast: Solar activity is expected to continue at very low levels. - Geophysical Activity Forecast: The geomagnetic field is expected to continue at quiet to unsettled levels with isolated active periods through 03 March. Quiet levels are expected on 04 March as the high speed solar wind stream rotates out of a geoeffective position. Quicklooks ---------- 4942 MKW8 ACIS-I NONE OK 4824 SDS 1321+..
