Subject:
NSA/SKYRAD/C1 - IRT mirror heater failure
DataStreams:nsaskyrad60sC1.b1, nsaskyrad20sC1.a0
Description:
The heater of the IRT gold mirror failed due to a broken wire (that probably occurred on 
12/13 during maintenance of the solar tracker) allowing snow and frost to accumulate on 
the mirror until it was cleared during daily preventative maintenance. The problem was 
corrected when the heater wires were replaced.
