March 2023 News research

Hi Everyone

 

Please find this month’s News and Starcharts attached along with all the interesting research.

 

There is a good look at the Trappist planets that I myself still need to read, these papers also tie in well with the Exo Venuses. Following on from that a few goon ones on Exo planets too. With all the posts about starlink it’s been a real interest for many people and there is a good paper on the issue here too. I feel like I have a lot of reading to do this month. Amazingly it’s a nice mild clear night tonight too here in Wellington, we might be in for a stormy winter too.

 

Thanks Edwin
