Moon phase

Friday 26 May 2017

Messing around with Jupiter last night. Moon to the left is Europa.

Another shot from last night with Io transiting the surface of Jupiter. It is sometimes hard to see the moons against the surface of the planet. But here Io is quite visible. This is because the limbs of the planet are subject to a phenomena known as limb darkening. This means that the moon stands out against the relatively dark limb. I'll process and post a shot from later in the night where Io is very difficult to identify.

Here is the list of our forthcoming meetings.

Hi all, just testing. Might be an easier way to let us all add stuff and take comments etc that's not FB.
What you think?
