[APBeta] Jupiter and the moons

[Bob]

If I am following you correctly with the time and date, S&T java applet is
correct. Only Ganymede and Europa visible.  AP and the others also agree. Io
behind, Ganymede and Europa transiting the face, and Callisto is east of
Jupiter in Jupiter’s shadow.

Paul, thank you for looking into this.  I took S&T at their word
(kinda) and looked at Skymap and it was right, but after I got home and
looked at this email, I loaded up Sky6 and saw the same thing. Now I have no
clue when this event that S&T is reporting even happens
:)

In the future, I am going to triple check myself before emailing :)
