Libration calculator?

Recommended Posts

Just wondering if there was a simple libration calculator on the web, or a list of the times that we can see more of the polar regions of the moon, a little peak of whats round the corner so to speak :)

It shows you the libration of the moon but does not tell you when this is at it's greatest, maybe I'm asking to much I don't know.

The CalSky website gives useful lunar information. Librations are given as angle of tilt and position angle. May be worth a look.

Follow the Moon - Apparent View/Data menu option

Mick, the floating arrow in the VMA shows where libration is favorable, but you need to look at the "Libration in Latitude/Longitude" numbers on the 'ephemeris' tab to see how favorable things actually are.

The numbers tell how many (negative) degrees over the limb we can see... the lower the number, the more favorable the libration. Best i've ever seen was almost -8. If you were looking for favorable libration predictions on specific features though, i'm not sure if the program does that or not.
