Sector Notes
Noted Issue |
Description |
Instrument issues |
The spacecraft passed through the shadow of Earth from approximately TJD 1940.38 – 1940.48. The instrument was not turned off, and other than the instrument heaters turning on resulting in a minor pointing offset, there is no indication that science quality was affected.
|
Spacecraft pointing |
In orbit 1 of Sector 23, anomalously high pointing jitter was observed for about 1.5 days before the momentum dump starting at ∼ TJD 1936.15. The peak-to-peak amplitude of the jitter is less than 1.5 arcseconds on 2 minute timescales.
|
Scattered light |
Camera 1 suffered from strong scattered light signals at the beginning of orbit 53 and orbit 54, and so Camera 4 alone was used for guiding during this sector. The Earth is a significant source of scattered light at the start of both orbits. The Moon also passes close to the field of view of Camera 1 during orbit 54.
