1BMSDiffuse CM2212/21/201307:00:0012/21/201316:22:00Due to a scheduled NREL power outage, to upgrade campus electrical infrastructure, The following BMS instruments were not pointing at the sun during this time: Direct NIP #1, LI-201, LI-190, NIP RG780, TWC; and the following instruments were un-shaded: Diffuse CM22, CUV4, CG4. The Middle Sci-Tec tracker for these instruments were temporarily put on a secondary UPS which failed immediately.
2BMSDiffuse CM2203/02/201313:06:0003/02/201318:24:00Due to a scheduled NREL power outage, to upgrade campus power capacity, The following BMS instruments were not pointing at the sun during this time: Direct CH1, NIP #2, NIP #1, LI-201, NIP RG780, CUVA2, CUVB2, TWC; and the following instruments were un-shaded: Diffuse 8-48, PSP, CM22, CUV4, PIR, CG4. The Sci-Tec tracker for these insruments are protected by UPS, however the battery depleted at 13:06 MST (the power outage started at 8:06 MST)
3BMSDiffuse CM2205/26/201206:15:0005/26/201207:12:00Due to a planned power outage for SRRL electrical work, the following BMS instruments were not following the sun: NIP #1, RG780 NIP, LI-201, TWC Photometer and the following instruments were not shaded CM22, CUV4, and CG4.
4BMSDiffuse CM2209/08/201108:23:0009/08/201109:38:00Due to a planned power outage for SRRL construction activities, the following BMS instruments were not following the sun: NIP #1, RG780 NIP, LI-201, TWC Photometer and the following instruments were not shaded CM22, CUV4, and CG4.
5BMSDiffuse CM2205/07/201105:55:0005/09/201107:58:00There was a planned power outage for SRRL construction activities that started at 5:18 MST. Unfortunately, the backup generator provided to SRRL was providing bad power to the UPS powering the Sci-Tec trackers, therefore the UPS failed at 5:55 MST. Unfortunately, when normal AC power was restored at 11:45 MST, the Sci-Tec trackers had lost all their configuration due to UPS cycling on and off during the outage, therefore were not tracking. The tracker settings were restored on May 9 at 7:58 MST. The following BMS instruments were not pointing at the sun during this time: Direct CH1, NIP #2, NIP #1, LI-201, NIP RG780, CUVA2, CUVB2, TWC; and the following instruments were un-shaded: Diffuse 8-48, PSP, CM22, CUV4, PIR, CG4

Tracker failed to automatically reposition when power was restored on 11/5/2005 at 5:02 MST, due to failed internal battery. The following instruments were UNSHADED: Diffuse CM22, Diffuse UVB-1 and the CG4. The AOCS was not pointing at the SUN.
18BMS010034Diffuse CM2207/23/200510:16:0007/25/200507:07:00Sci-Tec Tracker #2 rotated the wrong direction and hung up on the signal cables, due to a scheduled NREL power outage on 7/23/2005 at 5:33 MST. The following instruments were UNSHADED: Diffuse CM22, Diffuse UVB-1 and the CG4.
19BMS010034Diffuse CM2207/10/200505:56:0007/11/200508:00:00Sci-Tec Tracker #2 rotated the wrong direction and hung up on the signal cables, due to a momenatary power loss. The following instruments were UNSHADED: Diffuse CM22, Diffuse UVB-1 and the CG4.
20BMSDiffuse CM2205/02/200313:45:0007/03/200308:30:00On May 2, 2003, the shade on the CM22 and PSP was removed during BORCAL, which caused the diffuse instruments to measure global. However on May 5, 2003, it was decided not to corrupt the baseline diffuse measurements with "global data", so the instruments were disconnected and/or shorted at the baseline datalogger connection. The instruments were later returned to normal service on July 3, 2003. All data during this time is bad or bogus.
21BMS010046Diffuse CM2208/24/200209:15:0009/02/200217:30:00The shading ball on the CM22 was removed to allow the instrument to be calibrated in BORCAL 2002-04. Affected times (MST) were: 8-24-02 9:15 to 14:30, 8-25-02 10:00 to 15:00, 8-26-02 7:15 to 15:00, 8-27-02 10:15 to 12:45, 8-30-02 5:30 to 13:35, 9-2-02 10:00 to 17:30.
