Anyone on the list proficient with handheld GPS units? I'm trying to plot tonight's ISS Moon transit and would like to ask an expert if what I'm trying to do can be done. Patrick
I'm assuming you have plotted a ground track and want to find the right place to stand to view an occultation-transit.
TerraServer Advanced Find has an option to put in lat and long by decimal degrees. It returns a photo and topo map. http://terraserver.homeadvisor.msn.com/AdvFind.aspx
MapQuest has a similar service but returns a street map.

P.S. -
I ran the ISS through CalSky and do not show a moon crossing tonight. Patrick, how about sharing some _times_ - or are you going to keep it yourself -:) ?
P.P.S. -
CalSky is showing a Sun crossing on March 4. CalSky also has a link that takes you right to the best observing position, which for March 4, is the Jordan Park at 900 South and 900 West:
16h56m33.84s ISS Crosses the disk of Sun. Separation=0.015° Position Angle=152.1° Angular Velocity=10.9'/s. Transit duration=2.95s Angular diameter=17.8" size=73.0m x 44.5m x 27.5m Satellite at Azimuth=247.9° WSW Altitude= 14.9° Distance=1041.9 km Satellite apparently moves to direction 350.6° Map: Longitude=111°55'05" W Latitude=+40°44'51" Distance=0.32 km Azimuth=150.1° SSE Path direction: 60.1° ENE ground speed: 11.592 km/s width: 11.9 km max. duration: 2.9 s
However, CalSky is also showing a ISS manuvering burn in a few days. Although the burn is taken into consideration, the March 4 transit should be checked to see if the orbit holds.
