Subject:	SGP/QCRAD/E20 - Tracker alignment issue
DataStreams:	sgpqcrad1longE20.s2, sgpqcrad1longE20.s1, sgpqcrad1longE20.c2, sgpqcrad1longE20.c1
Description:	Tracker appears to be out of alignment or inoperative during these times. The short_direct_normal (NIP) and down_short_diffuse_hemisp (8-48) data appear to be bad and not recoverable. There were no instrument DQRs on this problem at the time this report was submitted.
Suggestions:	null
