SGP/MFRSR/E8 - Shading problem

A shading problem in the afternoon is noticeable from 2030 until sunset.
The 14th is about the earliest definitive day, but there are subtle hints
of it going back to the 1st.  As time progresses, the shading problem begins earlier and 
earlier, starting at 1900 just before the ending time of this DQR.

Avoid data from 1900 to sunset.
