SOT shift report 2004-04-16 L1730 Written at 2004:107:13:46 UTC = 09:46 AM Apr-16-2004 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 04638 continuing from yesterday, Cassiopeia A 2004:105:20:09, ACIS-S NONE - 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 very low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: The solar flare activity level was low. A single C class event was recorded yesterday.(http://www.dxlc.com/solar/) CMEs reported for past two days: April 13-15: No fully or partly Earth directed CME observed. CMEs originating from a few days behind the northeast limb indicate that an interesting region could rotate into view in 3-4 days' time.(http://www.dxlc.com/solar/- Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 1.04e+05 1/3465.2 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.81e+00 1/52 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 1.47e-02 1/53 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 4.14E+06 1/242 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.
