TWP/TSI/C2 - Shadowband misalignment
DataStreams:twptsiskyimageC2.a1, twptsicldmaskC2.a1, twptsiskycoverC2.b1, twptsimovieC2.a1
Description:
The mirror was continuously rotating and communication with the control board failed. As a 
result, the sun was not being blocked by the shadowband. The ethernet-to-serial adaptor 
was replaced.
Suggestions:
