August 8 and the dewpoint is 21F. Better get out there!
For a couple hours, the seeing consisted of very large and slow-moving waves,
which make the stars twinkle a lot, but can actually be "looked through" to see
planetary detail. Since all of the Jovian moons were in tight, I took a couple
images two hours apart. The first one shows the Great Red Spot on the
meridian, with Europa to the left and Callisto to the right. Ganymede is
behind the planet. It is rare to have the two outermost moons so close to
Jupiter

In the second image, Europa is casting the shadow, and Io has moved in to join
Callisto. The remains of the impact are apparent near the south pole.
