Subject:
NSA/TSI/C1 - Mirror frozen
DataStreams:nsatsicldmaskC1.a1, nsatsiskyimageC1.a1, nsatsiskycoverC1.b1
Description:
The mirror was not rotating so the shadowband was not masking the sun. This appears to 
have been caused by snow that was melted by the mirror heater and then re-frozen by high, 
cold winds.
