Details/Specifics of Change:

On 2 June 2009 on orbit 1637 around 1352 UTC, NOAA plans to reconfigure NOAA-19 APT channel A. On an orbital basis, the MIRP will be instructed to select AVHRR channel 2 for APT channel A when crossing over the southern terminator, from night to day, switching from an IR to visible channel. The MIRP will also be instructed to select AVHRR channel 3 for APT channel A when crossing over the northern terminator, from day to night, switching from a visible to an IR channel. APT channel B will remain set to contain AVHRR channel 4 data.

In other words:
APT Channel A will contain channel 2 data in daylight and channel 3b data in night
APT Channel B will contain channel 4 data at all times.
