From the SSD message: On December 3, 2011 (DOY 337) at 21:25Z, there was an increase in the NOAA-17 HIRS filter motor current and temperature. The motor current increased approximately 20mA to 170mA and later dropped back towards its previous level. There was a few tenths of one degree increase in filterwheel temperature. This anomaly, considered as a sign of aging of the HIRS filter motor, mainly affects the HIRS longwave channels. These channels have escalated but stable noise levels. | From the SSD message: On December 3, 2011 (DOY 337) at 21:25Z, there was an increase in the NOAA-17 HIRS filter motor current and temperature.

*'''28 Jan 2013''' [http://www.ssd.noaa.gov/PS/SATS/MESS/MSG0252318.02.txt NOAA-17 HIRS Outgas Test] several orbits of lunar view Space Look data will be collected surrounding an extended duration outgas. The associated data outages will not impact GEOS-5 since N17 HIRS3 is no longer used. | |||
