       Geminid Meteor Shower, Dec. 13/14, 2004 - Greenbelt, Maryland
                   Lat. 390016N  Lon. 0765233W - G.W. Gliba

   We had clear and cold conditions in Greenbelt for the Geminids, and I was 
able to get in a couple hours of observing before midnight. The best Geminids
seen were of -3, -2, and -1 magnitude, but several were 0 and 1st magnitude.
Below is a short breakdown of what was seen, followed by 5 minute bins for the
Geminid meteors seen.
