Today's 2 topics:

- NASA classifies 2023 SZ1 as a Potentially Hazardous Asteroid since it is larger than 140m in diameter and on its current path can come to about 6 times the Moon’s distance from us.Fortunately on its current path 2023 SZ1 will not come any closer than 42 times the Moon’s distance from us until after 2171.

- Marcel Drechsler, Xavier Strottner, and Yann Sainty’s image of our neighboring galaxy, M31, in Andromeda won the 10,000 British pound Astronomer Photographer of the year award for 2023. Amazingly their image revealed a huge, previously unknown arc of hot doubly ionized Oxygen gas.
