“For the first time, I’ve seen Luna in a GOES photo! Maybe this is commonplace, but I’ve only seen it this once in roughly 20 years of looking at your site. Luna was in GOES East at 2345H Oct 31, and in no others in the sequence. It showed just above the horizon over Vancouver Island, in all wavelengths.”
The GOES-13 (GOES East) 0.63 µm “visible channel” image (above) did indeed show a crescent of the Moon being illuminated just off the Earth’s horizon late in the day on 31 October 2010. A wide band of cloudiness moving over much of British Columbia and the Pacific Northwest was associated with a frontal boundary and an upper level trough of low pressure over that region . As it turns out, the Moon can actually be seen on GOES images a handful of times every year, depending on the viewing angle of the satellite in relation to the position of the Moon (for example, see http://cimss.ssec.wisc.edu/goes/blog/archives/2106).
The GOES-13 3.9 µm “shortwave IR image (above) showed that the illuminated portion of the Moon exhibited very hot IR brightness temperatures (dark black enhancement) — the maximum value indicated using McIDAS was 340 K. The very hot sunlit surface of the moon can actually reach temperatures of 383 K / +110º C / +230º F, while surface temperatures on the very cold “dark” side of the moon can fall to 93 K / -180º C / -292º F.
The GOES-13 6.5 µm “water vapor channel” image (above) showed a rather interesting pattern of banded gradients — this was due to the fact that the water vapor channel detectors are designed to sample much colder features, so the extreme heat of the illuminated moon surface caused a supersaturation or “roll-over” from hot (black) to cold (white).
The GOES-13 10.7 µm “IR window channel” image (above) also displayed very hot IR brightness temperatures across the sunlit portion of the Moon (as high as 330.5 K).
