SGP/SIRS/E27 - Tracker Misalignment

Suntracker failed at this facility. The suntracker was reset on
                  9/17, but this only temporarily fixed the problem and the tracker 
                  began failing again 9/18.  Tracker was reset and realigned on 
                  10/15/03 17:30GMT and has been operating properly since.
