ENR CTIO 1.5-m 2019-05-25

Date: 
Saturday, May 25, 2019
Telescope: 
CTIO 1.5-m
Submitter: 
Fred Walter
Submitter Email: 
frederick.walter@stonybrook.edu
Observer Support: 
None
Night Assistant: 
None
Problems: 

The Chiron controller overwrote files on 2 occasions. Seems to correlate with changing the number of exposures on the fly.

On 2 occasions the tracking acted up. Both times followed a slew - the telescope failed to stop at the target, and started drifting off to the east. I recovered by turning off the drives and the tracking, and then re-executing the slew.
