SOT shift report 2001-11-01 L833 Start at 2001:305:13:23 GMT = 2001 Nov 01 08:23 am EST End 11:00 am EST SOT Lead Ed Kellogg PLAN ---- OBSID 02221, 53W002 CLUSTER 2001:305:13:41, ACIS-S NONE - GALAXY AND CLUSTER BUILDING AT Z = 2.4 - the richest spectroscopically confirmed high-redshift (z>1)galaxy cluster, at z = 2.4, looking for evidence of diffuse X-ray emission from protogalactic winds and/or nascent intracluster gas. RADIATION SUMMARY Observed Limit ----------------- -------- ----- ACE 2 hr fluence 2.4e6 3.6e8. GOES-8/P2 4-9 MeV protons `P4GM' 0.07 95. GOES-8/P5 40-80 MeV protons `P41GM' 0.01 0.78 *ACIS* Orbital fluence (since perigee) 3.0e7 1.0e9 EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 0.0 10.0 P4GM (protons, 5.0 - 8.3 MeV): 0.0 300.0 P41GM (protons, 41 - 53 MeV): 0.0 8.47 ACIS focal plane temperature -119.7 at 08:13 am EDT. REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- 3 fids, 5 stars 1517 2221 SSR dump complete 1538 Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Dumps not current Data loss - Load is good -> 309/0140 CAPs - Next passes 1501-1545, 1820, 0100 MP: NOV05D load ready for approval. NOV12 being worked; there are issues with constrained observations, and this load includes the Leonids event. S/C: EPHIN and its housing exceeded yellow T limits, +10 C from its normal peak. It appears related to attitude. There are a number of temperatures creeping above yellow limits. It appears to be caused by a combination of a longterm upward drift and recent long attitude holds at hot sun orientations. Roger requested a tech briefing on all T limits. We will test the momentum envelope expansion patch Monday. Installation is planned for 12 Nov, 7-11 pm EST. GOT: Ron Wines reports he is planning to change all OCC office net IPs. This will be briefed at the Flight Director Board today. Accessible servers such as lucky, and printers will not be affected. DATA: - SOT: Proton rates are quite low. Flare activity has been moderate. The region rotating into view at the southeast limb was the source of a long duration M3.0 event which peaked at 01 Nov 2001 12:20 UTC. This bears watching closely. 0-20% chance of a CME arriving within 96 hrs. 60-100% chance of M and X class flares in the next 48 hours. Unagi has a new hardware configuration. It appears to be working fine for this SOT Lead shift, although its ability to receive ACA telemetry is not being tested at the moment.
