TWP/TSI/C3 - controller board failure
DataStreams:twptsimovieC3.a1, twptsicldmaskC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
The mirror control board failed and was replaced with a spare. Several images were 
collected in the iterim that should be ignored. These images include periods when the sun was 
not masked by the shadowband, the camera lens was covered by red tape to protect the CCD 
from direct exposure to the sun and, the instrument was inside the shop for repair and 
testing.

TWP/TSI/C1 - rust spots on mirror
DataStreams:twptsicldmaskC1.a1, twptsiskycoverC1.b1
Description:
During the evening of 7/8/2006, something caused several rust spots on one side of the 
hemispheric mirror which continued to grow in size and to be interpreted as clouds in the 
processed images. This problem was corrected during a site visit when the mirror was 
replaced.

TWP/TSI/C1 - high control board temperature
DataStreams:twptsiskycoverC1.b1
Description:
The TT8 control board temperature was high, ~50C, so that the cooling fan was constantly 
on. It appears that the heat sinks were not transferred from the original board to the new 
one when it was replaced. The problem was corrected when heat sinks were installed.
