OCRs:

DOY 148 (05/28/2013)  1625-1928z  CRIS-011
The Image Intensifier was powered on after being automatically
safeguarded during the last week's solar activity (Thursday 5/23/2013
01:30z, DOY 143).  This OCR was last executed on 03/12/2012.

This is the third time the CRIS Image Intensifier has safeguarded during
the current solar max (2012-2013).  From 2000 to 2006, the Image
Intensifier had safeguarded 16 times.
