Is it possible to use that program to predict artificial earth
satellites passing in front of the Sun?

I mean, given a pair of exact coordinates for my location and a time
span, I want a list of dates/times for when a satellite passes in
front of the Sun. Is this possible?

Carsten, I just tried with Cartes du Ciel: it should be possible with
some patience (maybe more than some...), refreshing the satellites
passages asking to show also those during daylight time, then
shrinking the fov to zenital projection and looking at the calculated
path of the satellite. If you are lucky, some pass close to the sun
and then you can focus on that. I'm not sure I explained myself...
Good luck...

Thanks, I understand what you mean, but I was hoping for something more automatic. Essentially, the program should calculate the angular distance between the Sun and each satellite in its database and classify it as a transit event when the distance is less than a certain angle tolerance, and the sun is still above the horizon. Over a some days or weeks there should be a few such events I imagine, and these might for example be listed in a timetable.
