SOT shift report 2003-09-26 L1527 Written at 2003:269:13:19 UTC = 09:19 AM Sep-26-2003 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 60543, ACIS CTI measurement. RADIATION SUMMARY ----------------- Solar soft proton flux is Very low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity was low. There were two C class events yesterday. CMEs reported for past two days: September 23-25: No potentially geoeffective CMEs observed.

S/C: - GOT/IST: - DATA: The upgrade to DS 7.0 is working mostly OK, with some small bugs being worked out. SOT: Still having some problems with the coot ACA display. The star image ACA display was not working during the last pass. After logging out and back in, the pass was finished, so its function could not be verified.
