1. GOES-15 SOUNDER OPEN GIRs 11/4/2010

2. GOES-15 SOUNDER GIRs PSPOT-0003 PSPOT-0004
Striping on First Public IR Sounding
Noticed first on Channel 15, and then on other SW channels.
7/21, 7/28 – Switched to Side2 and back with no remedy.
PSPOT-0004
Signal Jumps in GOES-15 Sounder MW #2 Detector Data
Observed during scanning (dynamic) and star (static) operations.
In spec with less than 10 counts jumps. Not comparable to GOES-14 loose beam extending lens problem.

3. GOES-15 SOUNDER GIRs PSPOT-0005
Sounder Patch Temperature Anomaly Following Yaw Flip
Patch Temperature Control was lost right after Yaw Flip and patch reached 99 C (102 C later)
Analysis concluded potential dislocation of roll blanket between the cooler and the FW bucket
Operational Remedy – Yaw Flip very close to each Equinox
Operational Impact (Twice per year)
Out-of-spec performance up to 28.5 hours with partial (~70%) scheduled products due to INR recovery.

4. GOES-15 SOUNDER GIRs PSPOT- 0006
GOES-15 Sounder SW Det 2 Line to Line Relative Accuracy
Detector 2 of the GOES-15 Sounder shortwave channels is exhibiting offsets which cause degraded line-to-line relative accuracy performance. Channel 14, Detector 2 is the only channel to exceed the specification referenced in S , paragraph
ITT is still characterizing.
