Subsystem History:

Date	Time	Component	Description
08/06/2007	18:49:00		HIRS Cooler Heater Turn On
08/06/2007	18:49:00		HIRS Filter Wheel Housing Heater Turn On
05/01/2006	12:40:00	ELECTRONICS	Turnoff HIRS Filter Wheel because of observed high temperatures. All other HIRS components remain on.
04/30/2006	22:45:00		Turnon all HIRS components to serve as resistor and reduce shunt stress.
06/23/2005	10:46:00	ELECTRONICS	Power off HIRS to reduce battery voltage drawdown during dark portion of the orbit.
08/30/2004	11:05:00		Turn on HIRS and MSU to add power load on spacecraft bus and reduce shunt stress.
07/25/2004	23:18:00		HIRS electronics autonomously powered off by battery undervoltage trip.
09/23/2002		FILTER WHEEL	HIRS Filter wheel ceased
08/21/1997			HIRS no longer being used
05/30/1997		FILTER WHEEL	Filter wheel motor current jumped and wheel out of sync due to lubrication starvation.
01/07/1992			HIRS science data unusable for producing sounding products due to possible couple with AVHRR motor jitter.
