Update #1 The N15
AVHRR global
imaging continues to be corrupted, however the issue appears to
periodically
correct itself at 0730Z daily and remain that way for several
orbits
afterward. This has been determined to likely be caused by the
\x93re-sync\x94 command
being sent daily at that time. Therefore, sending the \x93re-sync\x94
command every
orbit may correct this issue. This will be tested by engineering
on April 17,
2018 at ~1410Z.
Topic: NOAA-15 AVHRR
Global Image Outage
Date/Time Issued: April 16, 2018
2310Z
Product(s) or Data Impacted:
AVHRR Imaging Products
Date/Time of Initial Impact: April 12, 2018 0000Z
Impacts on Users and
Significance: AVHRR imaging products have been
impacted.
Date/Time of Expected End: April 13, 2018
1130Z
Length of Outage: ~36 Hours
Details/Specifics of Change:
The
N15 AVHRR global imaging became corrupted on April 12 at
~0000Z due to sync issues. This may be caused by erratic scan
motor current due to loss of lubricant. The problem appears to
have corrected itself, as the global image is no longer
corrupted. The issue is still under investigation.
