(http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity yesterday: Solar flare activity was moderate. A total of 3 C and 1 M class events was recorded during the day.(http://www.dxlc.com/solar/) CMEs reported for past two days: A rather faint partial halo CME was observed in LASCO images after the M2.8 flare at 13:07 UTC. The CME could reach Earth on April 23.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 1.28E+05 1/2815 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.38E-01 1/688 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 9.66E-03 1/81 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 2.04E+06 1/490 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

The APR2803 products will be out tomorrow. S/C: We had a good ASVT run on the gyro swap procedure yesterday. We'll present to the FDB for final approval this Thursday. The gyro got noisy again. It is now toggling between 140 and 150 mA. GOT/IST: - DATA: We are still investigating the unusual appearance of some data from obs 4434. SOT: GOES x-ray flux: Quiet today.
