Welcome to episode 223 of the Astrophiz podcasts. 
October is a fabulous month with lots of highlights for telescopers, astrophotographers, binocular and naked eye observers.
We have 'The International Observe the Moon' night, the Orionid Meteor Shower and some fine planetary action.
There is also a new comet C/2025 R2 (SWAN)

Comet C/2025 R2 (Swan) is a very recently discovered comet that is around magnitude 7 (which means it is binoculars only), but it is well placed near some very bright guide stars so it will be easy to find. 
Ian’s Comet R2 page shows where you can find its locations up till October 10, and there is some evidence the nucleus has split. What this means for brightness is uncertain, but it might either get brighter of disintegrate. 
You can find Ian’s Comet C/2025 R2 (SWAN) page at tinyurl-DOT-com/cometr2

Comet watchers will also hunt for Comet C/2025 A6 (Lemmon) which will be visible to the Southern Hemisphere low in the evening sky from mid-November 2025, with the best chances for viewing in the northern parts of Australia. While the comet will pass Earth in October, it remains a northern hemisphere object during that time; however, observers in the Southern Hemisphere can still catch it after sunset in mid-to-late November. 

and finally TCoronaBorealis still hasn’t gone nova, so keep watching it,

Astrophiz "Exceptional Interviews with exceptional scientists."
Brendan sometimes even gets how and why science works, and each month he conducts in-depth interviews with leading astro and space researchers. In each episode we feature Astrophysicists, Space Scientists, Particle Physicists, Data scientists, Antenna engineers, Instrument scientists, optical & radio astronomers, Satcomm engineers, project leaders and aurora hunters. For Astrophotographers, also each month we also hear from Dr Ian ‘Astroblog’ Musgrave who tells us when, where and what to look for in the sky over the coming weeks and explains astronomical phenomena in ‘Ian’s Tangent’.
This ongoing series has taken us through the history, theory and practice of radio astronomy from Faraday to Gravitational waves. Each episode includes the latest news roundup in this golden age of astrophysics. Enjoy! (& donate if you wish to help keep this podcast ad-free)
