SOT shift report 2003-12-08 L1600 Written at 2003:342:14:26 UTC = 09:26 AM Dec-08-2003 EST End 11:00:00 AM EST SOT Lead: Ed Kellogg PLAN ---- OBSID 04411, ACIS BACKGROUND 2003:342:08:54, HRC-I NONE - AO4 CALIBRATION OBSERVATION TO MEASURE THE ACIS CHARGED PARTICLE BACKGROUND with ACIS out of the focal plane. RADIATION SUMMARY ----------------- Solar soft proton flux is High. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity was low. A total of 4 C class events were recorded during the day, all from region 10510 behind the southwest limb: C2.3 long duration event peaking at 00:53.(http://www.dxlc.com/solar/) CMEs reported for past two days: December 6: Only a few LASCO images from early in the day are available. One CME from the southwest limb; does not look earth-directed. December 7 and 8: No partly or fully earth directed CMEs observed.(http://www.dxlc.com/solar/- Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 1.18e+07 1/30.5 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.03e-01 1/922 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 7.20e-03 1/108 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 2.61E+08 1/4 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

" Next passes 342/1550-1750 DSS 16 343/0250-0450 DSS 46 343/1300-1500 DSS 46" MP: Ken Gage reports that we aare doing the AICS undercover calibration. This is the third try, over a couple of months. Looks like we'll make it through the observation this time without a radiation shutdown. Brent is working on the DEC1503 load. He had difficulties with the new thermal constraints, combined with momentum and others, but products are expected out later today. S/C: There was some minor corruption of RT data, but the dump data were OK. GOT/IST: - DATA:Previously reported observation of "NGC" 520 was really Abell 520, a cluster of galaxies.
