Subject:
SGP/SIRS/E1 - Tracker inoperative
DataStreams:sgpsirs20sE1.a0, sgpsirsE1.b1
Description:
After a data outage 01/13 through 01/15, the solar tracker was inoperative until site 
operations corrected on 01/20.  

Another apparent power problem may have caused the tracker to not restart the morning of 
02/21.  It was reset by site operations on 03/04.

All tracker related datastreams are affected: short_direct_normal (NIP), 
down_short_diffuse_hemispheric (8-48) and possibly the down_long_hemispheric (PIR) although it is not 
apparent in the reviewed data for the affected timeframe.
