SGP/SIRS/E24 - NIP shaded near sunrise
DataStreams:sgpsirs20sE24.a0, sgpsirs60sE24.a1, sgpsirsE24.a2, sgpsirsE24.b1
Description:
The NIP is shaded by the EF laptop computer enclosure near sunrise during parts of the 
Spring and Summer.  This has occurred from 04/08 to 05/20 and from 07/26 to 09/06 every year 
since 2001 and will occur during these date ranges in the future as well.  The shading 
occurs for a few minutes each day between 1200 and 1300 GMT depending on the time of the 
year.  For the early dates, shading occurs a little after 1200 GMT and by 05/20 shading 
happens nearer to 1300 GMT. In late July the shading occurs near 1300 GMT and closer to 
1200 GMT by 09/06.
