The picture comes from the Alaska Volcano Observatory (aka place where “something called volcano monitoring” gets done). The ash plume from the eruption is the clearly visible dark smudge near the center of the picture. The image was taken by a weather satellite in geostationary orbit over equatorial Asia.

    The orbit seems too low and oblique to be GeoStat.

    Teddy, this is from a geostationary satellite (MTSAT-1R) over Papua New Guinea where Alaska is on the limb of the Earth. Here is a current visible image for the NE quadrant of the footprint:
