[Chaos-l] ISS Lunar transit, 12-1-2010

[walter fowler]

Just when I was getting ready to invite all the astrophotographers over here
for the big event ...  I checked on my Starry Night program and the moon
doesn't rise until about 3 am on Dec. 1.  But then why would the Google map
on the link show my house on the center line for the "occultation?"  It will
apparently be occuring below my horizon at that time so why is the map drawn
that way?  There has to be an error somewhere.  The invitation is on if we
can figure out if it's really going to happen.  Walter
