Hi ?ukasz,
I agree with you an I'll contact Valery Lainey for closer control of the data polynomes (we had some troubles with fortran tables formating ...)
We play with high precision ephemerids so ... ?
... give us 3 or 4 days.
Best regards,
Serge.

Hello
I think there is serious bug in Uranus moons data (code?). While Titania and Oberon positions seems to be accurate, then other 3 moons are in random place - especially Miranda is faar away from planet...
Look at attachement screenshot and photo taken by me at 14.09.2021 22:40 UT. For example stellarium shows correct data.

btw, I've updated debian package for Ubuntu/Debian

Hi to everyone, who contributed to version 4.1.0, and a huge thank you! That updates XEphem significantly. The quality of the updated positions of the Galilean moons can be checked e.g. by comparing Christopher Go's series of images of a triple transit of Callisto, Ganymede, and Europa on Aug 15th, 2021 (see ) with XEphem. During the transit there was also an occultation of Europa by Ganymede and a partial eclipse of Europa by Ganymede a few minutes later. All that is well reproduced by XEphem 4.1.0, whereas earlier versions didn't get the mutual events well.

Since openssl support is now included in 4.1.0, I had to install libssl-dev on my Ubuntu 20.04 system to get 4.1.0 compiled.

Thanks again and best regards,

Martin Federspiel
