Problems: 

At around 10pm (image #321554), the images went bad all over.  They were, in fact, completely saturated, although this was not immediately obvious from Kentools because it was displaying them at an apparent illumination level of 1000ADU.  The over-illumination was present in the r (saturating in 5s) and VR filters only.  After a fair amount of faffing about we discovered that one of the upward facing BCAMs was stuck on.  We tried running without the BCAM controller, but SISPI would not cooperate.  We turned the controller back on and I continued to collect data in the hope that the problem will not recur.  Time lost: 3+ hours.  See JIRA entry http://jira.ctio.noao.edu:8080/browse/BLANCO-142.
