5 min. VIIRS SDR/EDR impacted period: 2:26:26 to 2:31:30 UTC (sector rotation)

During the sector rotation:
- VIIRS onboard calibrators and Earth view sectors data acquisitions are shifted to allow the Moon image to be captured within the Earth view sector (off-nadir)
- DC Restore is turned off
- Dual-gain bands gain mode is switched from Auto Gain to fixed High Gain
- Bow-tie deletion is disabled
- The region affected is predicted to be the New Zealand area
