Subject:	SGP/Central Facility - Power Outage
DataStreams:	sgptsiskycoverC1.b1
Description:	Automated scripts show that these instruments were affected by a power outage at the central facility resulting in missing data. Most of the instruments came back online on March 6th but some took longer.

Subject:	SGP/TSI/C1 - shadowband misalignment
DataStreams:	sgptsiskycoverC1.b1
Description:	The shadowband was intermittently misaligned because the mirror control board was malfunctioning. The board was replaced on 12/23/2016 at 20:55 and on 2/21/2017 at 18:15.
