Mark your calendar for these interesting alignments, conjunctions, 
occultations, eclipses & meteor showers in the year 2005. Times are calculated 
for Phoenix, Arizona; other locations may differ. Most will be easy to see with 
the unaided eye, some very challenging -- take a look! Constructive comments 
and corrections welcome. This list may be copied and distributed for 
non-commercial use, but it must be credited to Joe Orman.
