Flight Operations Summary
Significant Spacecraft Anomalies: (The following are preliminary reports
of potential non-nominal performance that will be investigated.)
HSTARs:
12709 - SCI: GSAcq(1,2,1) results in Fine Lock Backup (1,0,1) @054/1519z
Observations Possible affected: ACS 36-39, Proposal ID#12310.
12711 - SCI: GSACQ(2,0,2) fails to RGA, Scan Step Limit on FGS 2 @054/1954z
Observations affected: WFC3 65, Proposal ID#12307.
12712 - SCI: GSAcq(1,2,1) required multiple attemtps,initially received a search radius limit
exceeded flag on FGS2. The second acquisition attempt to initially achieve FL-DV on both FGSs, but
was not able to maintain it. The third attempt was successful.@045/1359z
12713 - SCI: GSAcq(1,2,1) requires two attempts for FL-DV@045/1741z
