SOT shift report 2004-04-14 L1728 Written at 2004:105:13:43 UTC = 09:43 AM Apr-14-2004 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID CAL-ER (60277) 2004:105:13:54, Then we do Cassiopeia A 2004:105:20:09, ACIS-S NONE, a full orbit observation, eventually resulting in a 1 Ms exposure - a much deeper exposure that allows us to study nucleosynthesis and core-collapse using Chandra's full spatial resolution. RADIATION SUMMARY ----------------- Solar soft proton flux is low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity level was very low. No C class events were recorded during the day. (http://www.dxlc.com/solar/) CMEs reported for past two days: April 12-13: No fully or partly Earth directed CME observed. April 11: A fast, full halo CME was observed after a C9 event in region S380 early in the day. This CME is likely to impact Earth on April 14. Another full halo CME was observed near noon, its source was probably a few days behind the northwest limb.(http://www.dxlc.com/solar/- Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 8.61e+05 1/418.1 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 7.75e-02 1/1226 (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) (in perigee) (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

S/C: - GOT/IST: DATA: SOT: Coot is working again. Thanks to Tom, Rob and Wendy. Yobbo suffered an instant crash with black screen today at ~9:40 am. This is the machine where I write the shift report. It restarted autonomously and seems to be OK now.
