05/09/201300:00:00channel 18Or Orbit.
04/16/201316:05:18 Filter housing heat ON
04/16/201316:04:54 Filter Motor High Power
01/18/200519:15:00 Turn off HIRS filter housing heater since having it on did not improve channel degradation problem.
01/10/200516:00:00 Turn on HIRS filter housing heater
01/05/200512:00:00CHANNEL 3HIRS downgraded to YELLOW status because of long wave channel degradation.
01/03/200512:00:00 All HIRS longwave channels are currently out of NEDN noise specification by a large amount, and is affecting products. Degradation began in summer of 2004 and has worsened since then.
12/13/200401:15:00FILTER WHEELHIRS FIlter Motor Current & Temp surge. Period monitor also affected. Filter wheel synch not lost, imagery not noticably affected.
05/21/200400:00:00 Significant noise increase (exceeding specification) in many HIRS channels impacting image quality. Instrument health parameters nominal.
03/04/200419:00:00FILTER WHEELHIRS out of character filter motor current and temp increase. Period monitor and channel 5 & 10 imagery effects.
03/09/200100:00:00 HIRS cross track point error resolved - due to improper pre-launch alignment
10/12/200000:00:00 HIRS 1 pixel cross-track pointing error observed
