Submitter Email:

Observer Support: 
Hernan Tirado
Night Assistant: 
Rodrigo Hernandez
Also Present: 
Dustin Lang, Jeff Cummings, Rogerio Rosenfeld, Niall MacCrann
Problems: 

Problem with guider at 01:00 UTC. Noticed no guider data being displayed by GUI or telemetry.
Guider log was stuck on 'waiting for guider images’, even after 20s into exposure. Tried refreshing GUIs,
restarting guider, reset/configure SISPI. Eventually restarted SISPI. Guider GUI functioned as normal after restart.

 (30-minutes lost due to guider check-out).

Shutter error at 01:54 ... normal error processing commands followed - 4-minutes lost.

03:23 local: 4MAP failures (Faculty MAMAC 1): Usual recovery mode at zenith performed.

6-minutes lost

Nice work by Hernan T. and Rodi H. to fix the problems quickly. DJJ
