NSA/TSI/C1 - camera lens covered
DataStreams:nsatsicldmaskC1.a1, nsatsiskycoverC1.b1, nsatsiskyimageC1.a1
Description:
The shadowband was not properly masking the sun so the camera lens was covered on 4/13 to 
prevent damage to the CCD. On 4/20, the mirror was blown off by a snow storm and the 
instrument was brought inside for repair. The mirror was replaced, the lens uncovered, and 
the instrument reinstalled.

NSA/TSI/C1 - shadowband misaligned
DataStreams:nsatsicldmaskC1.a1, nsatsiskycoverC1.b1, nsatsiskyimageC1.a1
Description:
At several times during this period the shadowband did not mask the sun because the mirror 
was not properly secured. Attempts were made to align the mirror on 4/2, 4/3, and 4/10.

NSA/TSI/C1 - frost/condensation in lens
DataStreams:nsatsiskycoverC1.b1, nsatsiskyimageC1.a1
Description:
The sky image appeared hazy and was corrected by cleaning the neutral-density filter and 
lens of the camera. The determination of cloud fraction may be affected.

NSA/TSI/C1 - Mirror frozen
DataStreams:nsatsicldmaskC1.a1, nsatsiskycoverC1.b1, nsatsiskyimageC1.a1
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.
