Subsystem History:

Date	Time	Component	Description
09/13/1994		SCAN MOTOR	Motor current increased and black body channels no longer operating within normal limits
05/09/1991		SCAN MOTOR	AVHRR experienced three re-syncs, increase in motor current and noise in channel 3.
08/01/1989		OPTICS	Between latitudes 70 and 80 degrees, sun glint caused channel 3 black body temperature errors.
