A single C class event was recorded during the day.(http://www.dxlc.com/solar/) CMEs reported for past two days: June 2-4: No obviously geoeffective CMEs observed.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 4.86E+05 1/741 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.00E-01 1/950 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 3.00E-02 1/26 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 3.22E+05 1/3106 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

Some issues with hot restart star catalogs are being worked. We expect revised products out later this morning, and a review later today or tomorrow. S/C: The momentum unload went nominally yesterday, as far as we could tell so far. The duration was as expected. The gyro 1 current is still stable. The problem with poor star image quality noted in yesterday's shift report resulted in lots of gyro roll bias variability. This is likely to have been caused by warm pixels. It was of no consequence for science data, because it happened only during one obsid, 60715, not a science observation. Dan Shropshire reports that during yesterday's ASVT testing safe mode recovery, they lost control of the spacecraft in CPE mode. They were able to recover, but need more ASVT time to find out the cause and fix it. GOT/IST: The parking lot will be closed at 8 pm tonight.
