Subject:	SBS/MFRSR/M1 - Shading Issue
DataStreams:	sbsmfrsrM1.b1, sbsmfrsrM1.a0, sbsmfrsrM1.00
Description:	It looks like the shadowband may have slipped on the motor shaft during a weather event on 20110228. This resulted in a significant shading issue affecting data from 1900 UTC until sunset. It looks like maintenance made an attempt to fix this sometime on 20110305. We can't say exactly when maintenance occurred due to cloudy conditions. The maintenance was partially successful. 20110310 was the first clear day after maintenance, and we can see a minor shading issue affecting the hours between 2100 UTC and sunset. The last day we see this is 20110402 at sunset.
