Recent discussions on SeeSat involved transits of ISS across the moon and I'm curious as to how one can predict the ground path of such events. The are programs (e.g. Rob Matson's SkyMap) which can predict satellite transits from a particular observing location, and there are others that calculate the latitude/longitude of the sub- satellite point as a function of time, but I'd like to know if there is a straight-forward (i.e. not trial-and-error) way to calculate the geographic coordinates versus time where, say, ISS wculd be seen transiting the lunar disk. Thanks for any information. Clear and dark skies!
