I have the Delorme program & GPS, however the maps were done with Microsoft Streets & Trips. I created a Macro Express macro, documented at http://iss-transit.sourceforge.net/greenville.html, that automates the plotting of coordinates; download file is http://iss-transit.sourceforge.net/plotTransit.zip Using the one data point of a solar transit observed by Tom Wagner on 15 April, the TLE from http://spaceflight.nasa.gov/realdata/sightings/SSapplications/Post/JavaSSOP/orbit/ISS/SVPOST.html resulted in about half the position error of "the latest" OIG TLE, though the latter had about half (1 vs. 2 seconds) the timing error. http://iss-transit.sourceforge.net/images/SkyMap.gif shows your updated/OIG transit track (http://www.satobs.org/seesat/May-2003/0106.html) in the Dallas area, which is displaced about 1/3 mile northwest from my SVPOST-computed track, and about 2 seconds delayed relative to mine. ----------------------------------------------------------------- To unsubscribe from SeeSat-L, send a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@satobs.org List archived at http://www.satobs.org/seesat/seesatindex.html
