TWP/TSI/C2 - hazy image
DataStreams:twptsicldmaskC2.a1, twptsimovieC2.a1, twptsiskycoverC2.b1, twptsiskyimageC2.a1
Description:
Condensation in the camera lens and/or filter caused the sky images to be "hazy". The 
desiccant in the main enclosure was changed and the neutral density filter was cleaned.

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.
