Subject: | NSA/TWRCAM/C2 - Reflection on image during darkness |
DataStreams: | nsatwrcam3mC2.a1 |
Description: | During darkness, there appears to be a green light on the ground about 7 meters from the tower the camera is pointing at. We have deduced that this is, in fact, a reflection of a LED behind the camera in its housing. This spring, the camera will be slid forward towards the enclosure window eliminating this reflection. Since the images are of minimal use during darkness, this DQR is being submitted to explain the existence of the reflection. |

Description: | Condensation in the camera lens and/or filter caused the sky images to be "hazy". The desiccant in the main enclosure was changed and the neutral density filter was cleaned. |
