SOT shift report 2004-08-23 L1859 Written at 2004:236:12:45 UTC = 08:45 AM Aug-23-2004 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 04628, SN 2004dj 2004:236:10:25, ACIS-S NONE - Prompt Chandra Observations of Nearby Supernovae. RADIATION SUMMARY ----------------- Solar soft proton flux is Low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: The solar flare activity level was very low. No C class events were recorded yesterday. (http://www.dxlc.com/solar/) CMEs reported for past two days: August 20-22: No obviously Earth directed CMEs were detected in LASCO images.

S/C: We had a yellow limit on the MUPS tank pressure, PMTANKP. It dropped to 279.6, below the limit of 281.2. This is normal, from gas usage during momentum unloads. We keep the limit set just below the current pressure to watch for leaks. We'll reset the limit to a slightly lower value.
