DataStreams: | twptsiskycoverC3.b1, twptsicldmaskC3.a1, twptsimovieC3.a1, 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. |

Subject: | TWP/TSI/C3 - mirror continously rotating |
DataStreams: | twptsicldmaskC3.a1, twptsiskycoverC3.b1 |
Description: | The mirror/shadowband was rotating continously because of a serial communication problem with the control board. The problem was corrected when the Ethernet-to-serial adaptor was replaced. |
