Wu: Planner Command file: 03.06.19.12:42:00.cmd.log Activity: --------- 1) UVCS Recovery from Soft Safe Configuration Sequence: Manual SCI_SPEC: After recovery to Soft Safe configuration 19 June 2003 (UT), UVCS is recovered fully in preparation for return to normal operations. Though temperatures were still in a state of change, resumption of science was okay-ed for the following reasons: almost all temperatures were within 1 degree of pre-safe values (in many cases less than one degree), and the possibility of limited or no NRT throughout the day due to further HGA activities. Expected Limit Violation sheets submitted to FOT via SOC for any expected limit violations during this time. Nominal Limit monitoring resumed following resumption of science.
