Please find the attached usual newsletters, I haven’t had
this month’s star charts for this month, but if you’re in New Zealand you might
not have had much use for them anyway! According to the Met service it’s the
worst November ever recorded for Wellington and I’m sure not much better across
NZ. Its raining again at the moment and around 12c outside just after the
summer solstice here!
There is a range of interesting research out this month, the
possible discovery of a signal around Proxima really caught my attention, and
there are a range of links to news items on that one to follow up on. Andrew
has again taken a good look at the Chinese lunar sample return this month.
Well lets hope 2021 is a brighter year for everyone.
To finish off the year I have attached my best image of
Jupiter and Saturn
Cheers Edwin

Hi,
Currently there's a mag 7-ish comet in the morning sky (Comet Erasmus). It rises just before astro twilight. It could be a reasonable astrophotography target (albeit, we're fighting trilight down here in NZ). Here's an observation from J. J. Gonzalez Suarez (Spain) -
