Subject:	SGP/SIRS/E21 - Shadowband Misalignment/Tracker Failure
DataStreams:	sgpsirsE21.00, sgpsirsE21.b1, sgpsirs20sE21.a0
Description:	The solar tracker failed beginning around sunrise on 05/19/03 most likely during the previous nights reset. Failure time was approximate time of sunrise at 1000 on 05/19/03. The tracker was power cycled and RTS at 1415 GMT on 05/28/03.
