Subject: | NSA/TSI/C1 - camera lens covered |
DataStreams: | nsatsiskyimageC1.a1 |
Description: | The shadowband was not properly masking the sun so the camera lens was covered on 4/13 to prevent damage to the CCD. On 4/20, the mirror was blown off by a snow storm and the instrument was brought inside for repair. The mirror was replaced, the lens uncovered, and the instrument reinstalled. |

Subject: | NSA/TSI/C1 - Mirror frozen |
DataStreams: | nsatsiskyimageC1.a1 |
Description: | The mirror was not rotating so the shadowband was not masking the sun. This appears to have been caused by snow that was melted by the mirror heater and then re-frozen by high, cold winds. |
