Topic: NOAA-19 anomaly on the MHS/MIU

Date/Time Issued: October 12, 2017 2145Z

Product(s) or Data Impacted:  MHS Sounding Products

Impacts on Users and Significance: MHS sounding products are severely impacted

Date/Time of the Initial Impact: October 09, 2017 0425Z

Date/Time of Expected End: TBD

Length of the Outage: TBD

Details/Specifics of Change:

At approximately 0425 UTC, three temperatures on the NOAA-19 MHS have dropped significantly, one below it's red limit. The three temps that are cold are telemetered independent of instrument or MIU status. It is believed the MHS is safed and that the MIU is echoing the last packet it received prior to the MHS going safe. The anomaly is still being investigated.
