I see that I can use an URL like this to retrieve position data for LRO around the Moon:
But what I need is LRO longitude, to calculate when it will pass over a specific position, so I tried using Horizon to retrieve also position of a static point on Moon surface to calculate angular distance, but it dos not work, if it's static it has no ephemeris.
Maybe it could be possible using this page, but I was not able to figure out if an how:
For example this?
But in case it works, which would be the corresponding query URL?
