|---|
| 9 | BMS | | Diffuse UVB-1 | 10/29/2003 | 11:00:00 | 02/11/2004 | 00:00:00 | The Diffuse UVB-1 was removed from service and installed in the Global UVB-1 position. The original global instrument (S/N 921106) was returned to the factory, due to a residue that appeared inside the dome. A new dome was installed at the factory and the instrument was calibrated against the BMS Global UVB-1 on 2/10/2004 from 11:26 to 13:46 MST. This instrument (S/N 921106) is now installed in the Diffuse UVB-1 position. |
