5154	02:09-02:09	00:00	At the start of the night the cal software froze after the first exposure with no errors. Later in the night I attempted to run the cal script again and got an error, Non-reentrant handler.	Called: none Restarting the PFIP fixed the problem

Ops Comments	none

TO Comments	Cold front moved in, dropped temps and increased dust count to closing conditions.
