Did you know that the GOES satellites use the moon for calibration?
This image from GOES-17 on March 6, 2020, shows the moon rising over the northeast edge of Earth. Both GOES-16 and GOES-17 scan the moon regularly to help calibrate the visible channels on the satellites’ imager. The moon is a very stable and predictable target with no atmosphere.
However, normal processing of the satellite data removes all data beyond the edge of Earth. Special data processing is required to get moon images like this.
