Shadow transits in another time zone :-)
by Jane Houston Jones
Thanks to Bob Cz for wondering what the heck I was talking about with a
shadow transit last night. It was just a red barge in the SEB
preceeding the GRS which was not yet visible. I had forgotton to change
the location on my SkyMap Pro 9 and Palm software after returning from
the east coast - actually each of my Palms :-) had a different
location. The weird thing was that there was a star showing on my
software where Ganymede really was last night. The correct lineup was
all four moons on one side: Europa and Callisto close together, then Io
and then Ganymede.
I now return you to your regular programming while I, on the other hand
will be changing the location back to 37N 122W UT-8 on my various
astronomical software programs and various computers.
