jupiter's moon io disappears behind jupiter's western limb tonight around 10:24 p.m. eastern daylight time. then it reappears out of eclipse from jupiter's shadow, just barely off the planet's eastern limb, around 12:44 a.m. edt. at almost that same minute, jupiter's great red spot should be crossing the planet's central meridian.
