### OBSDATE ### 20120426 ### LOGDATE ### 120427 ### OBSERVERS ### MJI, JGR, YK, ACR ### WEATHER ### Looked clear, but some clouds came and went. ### LOCATION ### SUSI ### PROGRAM ### See if the new cleaned mirrors were performing. ### SIDEROSTATS ### n1 n3 s1 s3 ### TARGETS ### HR 2326 HR 4853 ### QUALITY ### Average ### PROBLEMS ### S1 Azimuth index had problems again. Even slewing from HR 2326 to HR 4853, it didn't end up in the right place (apparently a 1 degree error). The N3S3 fringes were horrible compared to N1S1, and the cart errors were more than 500nm often even with a 400 microns/s speed. Hopefully this is the cause of the problem and it can be fixed soon with the cart upgrade.
