SGP/MFRSR/E11 - Shading Problem

There was a minor shading problem affecting the data from 1500 UTC until 2000 UTC each day 
covered by the first period in this DQR.  

The shading problem on the afternoon of the 29th is unrelated to the one that occurred at 
the beginning of the month, but is included in this DQR since it is close in time.  Note 
though, that the shading issue on the 29th was much worse than from the 1st to the 6th.
