Neptune is the official CUAS newsletter, which we publish at irregular intervals. It contains information about the society, observing reports and most importantly contribution from its members (ranging from astronomy experiences, to poetry or completely astronomy-unrelated things). Past online issues are uploaded in the 'Past Events' section. There is a long series of back issues at the Institute of Astronomy Library (see also the History section).

We are looking to publish Neptune around the end of Lent 2017. So we need your astronomical contributions – photos, recollections, observing reports/hints/tips, poetry, reviews of interesting things you’ve read or seen, reports of trips you’ve been on or research you’ve done… anything that you think other CUAS members would like to see! If you have anything to contribute, please email them to Andrew Sellek ( by the end of February so that I can edit them together and publish by the end of term.
