Leonardo Paredes
Problems: 

At UT=7:30 the exposed images were not able to be digitized and we received alarm ID 2600.  After following the Troubleshooting guidelines and restarting the appropriate system (FCS) the problem persisted.  On the third retry, a new problem occurred: the GCS refused to start correctly and a red error light remained lit on the Interlock viewer.  Apparently the FCS was fine but now the GCS did not want to work.  We gave up at UT=8:30 due to target being at high airmass (2.10) which is very close to the telescope limits.
