Update #2 - JPSS J01 SMD Data Delay - Issued February 03, 2024 2124Z
Update #2: OSPO/MOD/Engineering has determined that the anomaly is the second reset of the NOAA-20 Spacecraft Command Processor (SCP). All instruments are in safe mode. Spacecraft recovery actions are underway. Stored Mission Data (SMD) and any associated products are unrecoverable. Data and advanced products will resume when the spacecraft is fully recovered.
Update #1 - JPSS J01 SMD Data Delay - Issued February 03, 2024 2031Z
Update #1: IDPS is not receiving any J01 SMD data until further notice. Engineering is investigating a J01 satellite anomaly. Missed data will not be recoverable.

Update #5 - JPSS J01 SMD Data Delay - Issued: February 06, 2024 2208Z
Update #5: VIIRS Cal/Val team is reporting a significant issue: longwave channels (M14-M16, I5), data quality flags at pixel level (QF1) are erroneous (labeled as poor qualify for good data). As a result, the VIIRS SDR team recommends that the data should not be released until this issue is resolved.
CrIS products are still under evaluation by the Cal/Val team and are expected to be released Wednesday, February 07, 2024.
OMPS products are still under evaluation by the Cal/Val team and are expected to be approved on the afternoon of Thursday, February 08, 2024.

Update #6 - JPSS J01 SMD Data Delay - Issued: February 07, 2024 2305Z
Update #6: The distribution of global NOAA-20 CrIS products will be delayed as it needs further coordination before its release.
Update #7 - JPSS J01 SMD Data Delay - Issued: February 08, 2024 1934Z
Update #7: All NOAA-20 OMPS Nadir Mapper (NM) SDRs and EDRs (V8TOz & V8TOS) products are approved for operational use and the NDE/PDA subscriptions for these products will be enabled at 19:30 UTC, February 8, 2024. Direct Broadcast (DB) users can use the equivalent OMPS NM Community Satellite Processing Package (CSPP) LEO products for operations.
OMPS Nadir Profiler (NP) SDRs and EDRs (V8Pro) will be enabled once additional OMPS SDR Look Up Tables (LUTs) are ingested into operations next week.

Update #9 - JPSS J01 SMD Data Delay - Issued: February 09, 2024 1641Z
Update #9: All NOAA-20 VIIRS and CrIS SDR and BUFR products are approved for operational use and the NDE/PDA subscriptions for these products will be enabled at 16:30 UTC, February 9, 2024.
Direct Broadcast (DB) users can use the equivalent CrIS and VIIRS Community Satellite Processing Package (CSPP) LEO products for operations.
CSPP Users should run the CSPP SDR update script (sdr_luts.sh) to download the new NOAA-20 VIIRS Look-Up-Table (LUT) that resolves the problem with I-Band 5 and M-Band 14-16 Quality Flags. The new LUT is:

Re: NOAA20 Anomaly
Update #11: Issued: February 13, 2024 2204Z Analysis by the Engineering and Calibration/Validation Science teams shows issues with telemetry data being received from the NOAA-20 VIIRS and CrIS instruments. The instrument vendors are recommending rebooting the CrIS instrument and restarting the VIIRS command processor. Each activity will result in data losses of approximately eight to ten hours.
The power cycle and restart of VIIRS will occur on February 20, 2024, and will result in an eight to ten hour loss of data on that date between approximately 14:00 UTC - 22:00 UTC.
The power cycle and restart of CrIS will occur from February 21, 2024, to February 22, 2024, and will result in an eight to ten hour loss of data on that date between approximately 14:00 UTC - 22:00 UTC.
