SYNOPSIS: ========= Weather was not permitting. Closed all night. GENERAL COMMENTS (see Problems below for details): ================================================== Other than clouds and rain most of the night, the only thing of note was that the telescope was tracked inside the enclosure to verify that indeed changing axes positions were being recorded in the headers of imager frames. They are. The afternoon checkout went smoothly, with all systems behaving normally.
