Three days ago (Sunday 11st March) in London using my new telescope I was able to see Jupiter and three of its moons. It was very clear and easy to spot. How can I determine the names of the moons I saw (and which one was which)? I would assume they were the Galilean moons - as they are the largest, making the easily visible, however, I am not sure which moons I would have seen.
This is how they lined up through the ‘scope :
. O .
where .=moon & O= Jupiter
Any help would be appreciated.
