SOT Shift Report 2006-12-11 L2699 Duration: 11 Dec 2006 08:30 EST - 11 Dec 2006 09:30 EST 11 Dec 2006 13:30 GMT - 11 Dec 2006 14:30 GMT SOT Lead: Tom Aldcroft ======================================== Plan ---- Do a science replan today and uplink new loads at an 8pm pass. See Notes. Events ------ No comm this shift. Notes from 9am meeting ---------------------- Ops: In Radiation Zone NO Current SI None, Finished ACIS-I Grating NONE Observation ID None, Finished 07998 Target None, Finished C-COSMOS1-5 Altitude 98.1 kkm Asc Radmon Disable 347/01:11z Next Radiation Zone 347/06:46z to 347/19:47z - DR: DSS-27 Station Unable to bring transmitter on line LAN Storm, station unable to configure equipment. Tried to change support to DSS-24 but they were experiencing the same problem. DSS-16 not available. No other station available. - As a consequence SSR-A will have rolled over to the B recorder. At the next opportunity the procedure to dump and recover to A will be executed. MP: - Science replan in work, with products expected out in a few hours. - Eight load reviews occurred over the weekend. FD and FOM extended many thanks to those who worked all weekend. Eng: - CAP 1017 was run to update the OBC tertiary database in order to provide more load during eclipses. - ACA PEA RAM error was out of limit for one cycle, but since there was no corresponding value in OBC telemetry it is likely to be a double-bit error. - SCS107 ran again over the weekend at 344:08:58 - OBA average temperature was toggling above the yellow limit for a period, related to the attitude after the SCS107 stoppage. Radiation: - The ACE and GOES radiation levels have been continuing a slow but steady decline (but see below) since the last of large flares from region 930. That sunspot region has produced only minor C-class flares in the last 2.5 days. - In the last 6 hours there is evidence for a sharp uptick in the softest ACE proton channels including P3. The noisy signature initially looked like backscatter, but this may be real. - Current rates support a return to science. - Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class activity from Region 930. - Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to active on 11 December. On 12 and 13 December, conditions are expected to be quiet to unsettled. The greater than 10 MeV proton event is expected to end in the next 24 to 48 hours.
