Astrophiz223-OctoberSkyGuide

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,
