TWP/TSI/C3 - controller board failure

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.
