| 1 | BMS | | Global 1-Axis CMP22 | 09/17/2021 | 15:13:00 | 09/23/2021 | 07:55:00 | For an experiment, the 1-axis and 2-axis trackers were placed in a 40-degree South Fixed Tilt, this affects the following instruments: Global Normal CMP22, SP-Lite2, LI-200R, WISER; Global 1-Axis CMP22, SP-Lite2, LI-200R, WISER |

| 2 | BMS | | Global 1-Axis CMP22 | 08/28/2021 | 15:58:00 | 08/30/2021 | 08:19:00 | There was a power dip at 15:58 MST on Aug 28, however 1-axis tracker was no longer tracking properly, its elevation was off throughout the weekend (which disagreed with the reported elevation from the tracker which was correct). Tracker was power cycled at 8:19 MST on Aug 30 and normal operation resumed. This appears to be a tracker firmware bug. |

| 3 | BMS | | Global 1-Axis CMP22 | 05/18/2021 | 15:00:00 | 05/19/2021 | 07:22:00 | The GFCI Breaker tripped on May 18 @ 15:00 MST, which powers 1 and 2 axis trackers and WISER spectroradiometers at that location. Cause of breaker trip is unknown. Breaker was reset on May 18 15:31 MST, however 1-axis tracker was no longer tracking properly, its elevation was about 19 degrees higher than it should be (both afternoon and the following morning, which disagreed with the reported elevation from the tracker which was correct). Tracker was power cycled at 07:22 on May 19 and normal operation resumed. |

| 4 | BMS | | Global 1-Axis CMP22 | 03/17/2021 | 17:32:00 | 03/19/2021 | 16:14:00 | For an experiment, the 1-axis and 2-axis trackers were placed in a 40-degree South Fixed Tilt, this affects the following instruments: Global Normal CMP22, SP-Lite2, LI-200R, WISER; Global 1-Axis CMP22, SP-Lite2, LI-200R, WISER. Also on 3/19, for a short periods (approx 5 min each), the CMP22 was shaded at 9:01, 12:07, 12:16, and 15:06 MST (approx start times). |

| 5 | BMS | | Global 1-Axis CMP22 | 11/17/2020 | 07:21:00 | 11/17/2020 | 07:45:00 | Due to a scheduled NREL/SRRL power outage, to replace a surge protection device on the SRRL building, The following BMS instruments were not tracking the sun during this time: Global Normal CMP22, SP-Lite2, LI-200R; Global 1-Axis CMP22, SP-Lite2, LI-200R |

| 6 | BMS | | Global 1-Axis CMP22 | 07/17/2020 | 14:58:00 | 12/15/2021 | 19:31:00 | DATA CORRECTED on 12/17/2021: Irradiances were increased by 0.675% due to revised BORCAL report for all BMS shortwave radiometers calibrated in 2020 and 2021. |
