Hi everyone

Please find all the usual, starcharts and newsletters attached along with some research papers too. With the news about Phosphine in the clouds of Venus I have added in some good ones on Venus for you to have a look at and read. Again Andrew has provide us with some great updates and there are lots of links to have a look at. Due to not feeling to well over the weekend I haven’t been able to do much of a write up on Venus myself this month but Paul Gilsters article provides a great overview and detail as always.

Anyway enjoy

Thanks Edwin
