12561 - SCI: GSAcq(1,0,1) at 362/22:13:46z and at REAcq(1,0,1) at 362/23:20:37z failed to RGA
control with Search Radius Limit exceeded on FGS 1.@362/2216z
Observations affected ACS 66-70, WFC3 67-70 Proposal ID #12064

SIGNIFICANT EVENTS:
Flash Report Venus Observation:
Section C of IP-219 was successfully performed approximately 362/02:34:10 to active the Post-Venus
Observation Macro. Macro #2 restored the safemode response back to Inertial Hold and restored the
Sunpoint sun-angle limit back to 46 degrees.
The second Venus Observation was successful with a nominal guide-star acquisition
