Flash Report 1 of 2 - Venus Observation #2 Operations Request 19000 was successfully performed 
approximately 022/14:22 - 14:23 to execute Macro 1, Section B of IP-219 Venus Observation Macros - 
Installation and Usage.   
Flash Report 2 of 2 - Venus Observation #2 Section C of IP-219 was successfully performed 022/18:58 
- 18:59 to active the Post-Venus Observation Macro #2 which restored the safemode response back to 
Inertial Hold and the Sunpoint sun-angle limit back to 46 degrees. Both of today's Observations 
were successful with nominal guide-star acquisitions.
