Best GRS Transit Reference?
Posted 29 June 2019 - 10:36 PM
The Android app Jovemoons works well for me.
This is the reference that I use the most. In fact, I used it tonight, and the app view matched up well with what I saw through the scope.

The Sky X Serious Astronomer compensates for the GRS as well. I have checked it out against Win Jupos and the GRS is in exactly the same position.
Starry Night 6 would as well but you have to manually update the GRS Longitude every 3 months or so. If I remember correctly, I had to go through WinJupos to get the longitude of the GRS.

This is very helpful to me so I'm moving it back to the first page. David

I think the present longitude for the GRS is 110*. That would have to be entered into the program.

Moving this back to the front page. Still getting some nice views of low down Jove as seeings been good enough to support 290X-370X . David

The results match the predictions of Sky&Telescope website and were quite reliable. Another bonus of this app is the ability to easily adjust the drift paramaters of the spot, because these tend to change over longer time periods.
You will also get predictions for surface features on Mars (Olympus Mons, Syrtis Major).
