[Edwin Rod]

Hi everyone

Please find all the usual star chart’s and newsletters attached along with a few interesting bits of research.

There is a good look at the search for the proposed outer ice giant this month and some great ones looking at habitable planets too.  The Leo labs tool looking at orbiting objects is lots of fun to have a look at.

 

Cheers Edwin
