12/21/200919:29:37 MHS to Standby, Channel H4 Gain to 3 dB, then to Scan Mode
12/21/200919:27:45 MHS to Standby, Channel H3 Gain to 2 dB, then to Scan Mode
12/21/200919:27:04 Transition to Warm Up Mode
12/21/200919:26:33 MHS SPE/SCE Power On
12/21/200919:25:51 Transition MHS to Power On Mode
12/19/200919:31:25 The MHS was recovered from the Fault Mode and is in Scan Mode
12/19/200914:25:16 While passing through the center of the SAA (14.3 South, 7.7 West at event time), the MHS entered Spin State. An above fault limit current was detected on the Flywheel Drive Motor and Reflector Drive Motor causing the MHS to transition to Fault Mode. Telemetry and science data indicate the N19 MHS behaved in a similar fashion to the MetOp-A MHS in its Spin State to Fault Mode events. EUMETSAT has already reviewed the data and given approval for recovery to Scan Mode efforts to begin.
