Subject:
SGP/SIRS/E4 - Shadowband Misalignment
DataStreams:sgpsirsE4.b1, sgpsirs20sE4.a0, sgpsirsE4.00
Description:
The solar tracker failed on 12/4, resulting in bad direct and 
               diffuse measurements. The tracker started working again on 12/8 
               without Ops intervention.  Technician maintenance checks on 12/3
               and 12/17 reported correct tracker operation.
