This is the AIRS, AMSU-A, and HSB weekly operations status report for Friday, November 15, 2024 (the end of week 1175 of the Aqua mission).

 
AIRS:  The AIRS instrument remains healthy with all voltages, currents, and temperatures as expected.
AMSU-A1:  AMSU-A1 is healthy except for channels 4, 5, 6, and 7.
AMSU-A2:  AMSU-A2, which provided channels 1 and 2 of the AMSU-A suite, suffered a non-recoverable loss of power on September 24, 2016 and is no longer operational.
HSB:  HSB has been non-operational since February 2003 due to a scanner anomaly.


Instrument activities since previous report:

An AIRS guard test ran on Monday, November 11.  Here is the timeline (UT):
   316/23:07:00 AIRS Guard Test begins (AIRS in CHECKOUT mode) 
   316/23:34:00 AIRS back in OPERATE mode

MODIS Lunar Calibration #238 was executed on Wednesday, November 13.  Here is the timeline (UT):
   318/11:18:00  AIRS put into READY mode prior to Lunar Cal
   318/11:18:15  Clear AIRS time-delayed queue (stop periodic command execution)
   318/11:18:30  Start periodic execution of focal plane temperature readout cmds
   318/11:18:45  Last DC Restore before Lunar Cal roll
   318/11:38:50  Start periodic execution of DC Restore commands   
   318/11:39:00  AIRS back in OPERATE mode
  

Upcoming events:

1) A new Optimum (normal operations) gain & circumvention table will be uploaded.
The table has been generated and is under review. 

Daily plots of noise levels for each AIRS channel are available on the AIRS webpage at https://airs.jpl.nasa.gov/mission/instrument-operations/.
A link there currently points to where the files are hosted at https://thunder.jpl.nasa.gov/nedt_trends/html/airs_channel_nedt_trends.html.
For each channel there are plots for the whole AIRS mission and for the last 2 months.
Going forward, weekly Ops status updates will be archived at the same webpage above,
and are hosted at https://airsteam.jpl.nasa.gov/report/latest and https://airsteam.jpl.nasa.gov/report/archive/.
