Starts at 11am. - Peer review for SCS107 patch to reduce risk during eclipses on x1165 at 10am Radiation: - Sunspot region 756 continues to grow and be a threat for M-class flares. At this time ACE P3 and GOES rates are very low, and there was no significant Solar X-ray activity over the last 24 hours. - Solar Activity Forecast: Solar activity is expected to be at low levels. Region 756 has the potential of producing an isolated M-class flare. - Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels for 29 and 30 April. Active to minor storm conditions are possible on 01 May due to the onset of a recurrent high speed coronal stream. Quicklooks ---------- 5921 NGC 4365 ACIS-S NONE OK 5441 RXJ0513.9..
