Full Moon (exact at 1:05 p.m. Eastern Standard Time). This evening the Moon shines below the dim hind feet of Leo.
And another! Io partially eclipses Ganymede with its shadow from 1:35 to 1:46 a.m. Friday morning EST. Ganymede will dim by a full 1.0 magnitude at mid-eclipse. They’re both to Jupiter’s west – with Callisto in the background between them! Callisto is normally 1.1 magnitude fainter than Ganymede (which is the one appearing closest to Jupiter). But at mid-eclipse Ganymede will look almost identical to Callisto, with Io clearly outshining them both.
