SOT shift report 2003-07-28 L1467 Written at 2003:209:15:01 UTC = 10:01 am Jul-28-2003 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 04184, ZWCL1215 2003:209:09:18, ACIS-I NONE - observing processes in the very cluster centers - HIFLUGCS is the best currently available local cluster sample in terms of homogeneous X-ray selection - objective is to constrain the density of the universe. RADIATION SUMMARY ----------------- Solar soft proton flux is High, after being very high over the weekend. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity was very low yesterday.(http://www.dxlc.com/solar/) CMEs reported for past two days: July 25-27: No potentially geoeffective CMEs observed.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 5.07E+06 1/71 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 5.17E-02 1/1838 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 8.55E-03 1/91 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 2.88E+07 1/35 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

We plan to do some MATLAB maintenance later today. There is a request to change the roll angle in obs3911 to try observing a new source. Feasibility will be checked this morning by FOT MP. S/C: We had our first eclipse of the season yesterday morning. It went nominally, except we did get battery polarity sensor glitches, as detailed in flight note 410, no cause for concern. The next eclipse is Wednesday. The gyro bias continues to drift, with no effect on pointing. We've seen several large shifts over the past few days, likely due to degraded star images in the ACA. We are processing the data further. Bill Davis reports that we will be submitting an update to the new gyro calibration shortly. GOT/IST: - DATA: Good work getting the TOO obs 3922 data processed quickly! SOT: The Sun is quiet.
