ENR CTIO Blanco 4-m 2013-09-24

Date: 
Tuesday, September 24, 2013
Telescope: 
CTIO Blanco 4-m
Submitter:

Observer Support: 
Catherine Kaleida
Night Assistant: 
Leonardo Paredes
Also Present: 
Pete Kuzma, Mauricio Rojas
Problems: 

One of our images (238306) had unusual donut shapes on some CCDs.  It was a 900s exposure in g, and there were some bright stars nearby.  We used a dither patter which I think is why this only showed up on one image.

No other problems
