TONIGHT!


  Nice sequence of clear nights we're enjoying.    Tonight when the sky =
is growing dark look to the southeastward.  You'll see the nearly Full =
Moon with a bright star-like object beside it.  That's Jupiter.


  As a further point of interest,  all 4 of Jupiter's Galilean moons =
disappear from view at about 1:47 a.m. ADT.  I realize that this is a  =
bit far into the night for some, however, it is a rare event.    Here is =
a neat animation which illustrates the event; the times are in Universal =
Time (Greenwich Mean Time is about the same thing).


  (  http://shadowandsubstance.com/  )


  Those with a small telescope can watch the event unfold, or at least =
see the moons move in toward Jupiter's disk.   At 9:00 p.m. Callisto is =
already behind Jupiter, with Europa and Ganymede to the east of Jupiter =
and Io ( I-O ) is on the west.  At about 10 p.m Europa overtakes =
Ganymede and moves in line in front of Jupiter's disk about 1:00 a.m.  =
Io also will have moved behind Jupiter at 12:44 a.m. Ganymede will be =
last, at 1:47.  With a large telescope Europa, Ganymede and their =
shadows could be observed crossing the front of Jupiter's disk.   To the =
small telescope, though, all four moons will be out of sight:  it is a =
rare occasion when this happens. =20


  Just before 3:30 a.m. Io re-emerges from behind Jupiter and its =
shadow.    Again, I suggest having a look at the animation.
