The transit predictions I get tell me various points to stand to see ISS cross the Sun, Moon and planets. They look like this: 11 Feb 13514 40.3668 -112.5347 11 Feb 13515 40.4081 -112.4595 11 Feb 13516 40.4485 -112.3875 But I've yet to receive a report where any of the points corresponded with a convenient location to set up a scope. Up to now I've used a spread sheet to interpolate between the points and then used a site on the web to plot the data on a map. It worked but it's time consuming. So I figured I might be able to plot the way points on a GPS receiver and just drive until I'm between those two points. Turns out you can. And, to make it even better the receiver even draws the line. So now it looks like all I need to do is plot two points from the predictions and then drive until I reach the line. Seemed to work in this evening's test run. Now I'm looking forward to trying it for real. Patrick
