These two image sets were taken about 90 minutes apart on the morning of July 19th through thick smoke from wild fires burning in Canada and the Pacific northwest. In the first image taken at 2:10 the Great Red Spot is rotating out of view to the lower right, Io is the bright spot against the gray limb darkening near the equator at left, and Io’s shadow is near the center. In the second image the Io’s shadow is about the leave the face of Jupiter and Io itself can be seen as a gray spot against the white equatorial zone.
