TWP/TSI/C2 - Mirror continuously rotating
DataStreams:twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1
Description:
The mirror began to continuously spin. Diagnostics were performed on the encoder, control 
board, and Ethernet adaptor. The instrument was removed on 1/2/2008 and shipped to Darwin 
for repair. The encoder and control board were replaced and the instrument was 
reinstalled.

TWP/TSI/C1 - Shadowband Misalignment
DataStreams:twptsiskycoverC1.b1
Description:
When the TSI was reinstalled on 4/22/2009, the shadowband was aligned relative to the 
enclosure but either the camera arm & housing was not plumb or the enclosure was not properly 
aligned with true north. This was corrected on 6/30 at solar noon.
