| 4 | BMS | | SolarSIM-D2 | 03/09/2019 | 08:40:00 | 03/09/2019 | 12:59:00 | Due to a scheduled NREL/SRRL power outage, to install power meters on the SRRL building, the following BMS instruments were down: 501A-UVA, TSP-700, UVSAT, UVSBT, SolarSIM-D2, CUVA2, WISERs, CUVB2, UVB-1, 501A-UVB, MS210W, SPN1, TSI-880, PGS-100, POM-01, TWC, ASI-16. |

| 5 | BMS | 107 | SolarSIM-D2 | 11/20/2016 | 09:15:00 | 11/28/2016 | 10:00:00 | Due to the low position of the sun in the sky during November, some of the sensors on the SolarSIM were being shaded by the CG4 pyrgeometer mounted on the tracker to the south of the SolarSIM. Spectral data during the 9:15 to 10:00 MST time frame will be bogus on these days. The instrument was mounted higher on 11/28/2016 to prevent future shading. |
