Notes from 9am meeting ---------------------- - Supports Completed: 9 (5 34 Meter, 4 26 Meter) - DSN DR's Created: N104742 DSS-27 RF Off commands being rejected by spacecraft. - OPS DR's Created: Failed CMD Load uplink attempt due to known Ground System Problem (CMD Destination Unknown Error) Cambridge Ops followed "work-around". - TECH DR's Created: Unable to turn spacecraft off at end of support None, spacecraft turned off with fourth set of turnoff commands Unknown After third set of RF OFF commands had station disable ranging. Resent RF OFF commands and they worked - SCS's Loaded: 4 - Good through: 2008:045:21:48:43.000 - SSR Dumps: 10 - Current Configuration (as of 42/1400): In Radiation Zone NO Current SI ACIS-S Grating NONE Observation ID 08037 Target 1062 Altitude 107.5 kkm Desc Radmon Disable 042/23:14z Next Radiation Zone 042/23:35z to 043/13:12z - Next Scheduled Supports (3): Time BOT EOT Site Station Antenna 042/1810-2025 1910 2010 CANBER DSS-34 34 Meter 043/0110-0300 0150 0250 CANBER DSS-46 26 Meter 043/1000-1250 1040 1240 CANBER DSS-46 26 Meter MP: - FEB1108B products were approved on Friday, but over the weekend a TOO was approved that will be inserted into the 4th load segment of FEB1108. Replan products are expected out today, with uplink required by Thursday. - Another TOO for FEB1808 was approved. Development of those products is pending the FEB1108 replan. Eng: - Problem with RF-off commanding coincided with a warning-low limit on the power amp 1 output power. - During a long dwell at forward attitude a number of caution-high limits were exceeded for components on the -Z side. There remains plenty of margin for all of these components and FOT engineering will evaluate adjusting the yellow limits. Radiation: - Solar Activity Forecast: Solar activity is expected to be very low. - Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels with isolated minor storm periods at high latitudes on day 1 (11 February) due to a recurrent coronal hole high-speed stream. Activity is expected to be at quiet to unsettled levels on days 2 and 3 (12-13 February) as the effects of the coronal hole high-speed stream wane.
