TO Commentsworked with high 0.3 particle count first part and later parts of the night; later particle count decreased below normal operating levels for parts of the night.


RA CommentsSR unable to attend, Shetrone covering the night. Working above old 0.3 um closure conditions. Probably should CO2 tomorrow. Was able to determine offset to the deployable imagers and took preliminary data from a star into DWFS8.
