News, research papers and Starcharts for August 2023

 

 

Hi everyone some interesting news and research out this month.

 

Venus Mercury and Regulus - Photo taken last weekend

A smartphone image here of the nice sunset and evening from Featherston, In the Wairarapa.

The conjunction of the 3 can be seen above the Rimutaka ranges in the evening sky, some due and smoke was in the air. Relative to where we live in Wellington the sky was much clearer and dark even from in the streets of the town, the hills block the glow of Wellington, the street lights were better shielded and dimmer too.

Cheers Edwin
