Jupiter’s moon Callisto appearing as a dark dot against the bright planet’s disc, was seen transiting Jupiter on April 4, 2021, 5 am local time. Another Jupiter’s moon, Io, the cloud bands, and the great red spot, are also visible in this photo. Very bad seeing conditions made it difficult to capture sharper views of the planet.
