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.

  • JPG data stream - documentation not supported(JPEG data stream - documentation not yet available)
