McIDAS images of GOES-15 (GOES-West) 0.63 µm visible channel data (above) showed the west-to-east progression of the lunar umbra (the Moon’s shadow) from a partial solar eclipse that occurred on 23 October 2014. The shadow was most obvious across the northern portion of the images, moving over Alaska, the Gulf of Alaska, western/northern Canada, and the far northwestern portion of the Lower 48 States of the US. The partial eclipse shadow could also be seen on GOES-13 (GOES-East) 0.63 µm visible channel images (below).

According to EarthSky.org the point of greatest eclipse (75% coverage of the solar disk by the Moon) was near Prince of Wales Island, Nunavut, Canada at 21:44 UTC. In a sequence of before, during, and after-eclipse AWIPS images of Suomi NPP VIIRS 0.64 µm visible channel data (below), a darkening of Canada’s Yukon Territory — which covered most of the center portion of the images — could be seen.
