Subject:
SGP/SIRS/E19 - Shadowband Misalignment
DataStreams:sgpsirsE19.b1, sgpsirsE19.00, sgpsirs20sE19.a0
Description:
The solar tracker appears to have failed on 8/28. Fuse replaced on 09/04/03 and tracker 
returned to service at 15:26GMT
Suggestions: 
Affected downwelling diffuse (DD) and direct normal (NIP) data is not recoverable.  

Downwelling IR (DIR) data should be used with the knowledge that the pyrgeomter is not 
shaded during this period.
