A Dance before the Laughing Giant

Jupiter Io transit 

Europa Transit of Jupiter
  
  The moon Europa, denoted by the tick marks as a bright spot against the North
Temperate Band was just beginning its transit across the disk of the planet
Jupiter. At about this same time the great red spot had just crossed Jupiter’s
meridian as the planet crossed my observing site meridian. I deemed this worth an
attempted sketch.
