Tweeddale Astronomical Society

Tweeddale Astronomical Society For those who enjoy viewing the night sky in the Tweed Valley. Hi and welcome to the Tweeddale Astronomical Society page.

Tweeddale Astronomical Society (TAS or 'TweedAstroS') is a newly formed group based in Peebles in the Scottish Borders. Our aim is to encourage anyone with an interest in the night sky, space exploration or just anything astronomical to get together and share their enthusiasm for the subject. We usually hold our main monthly meeting on the 3rd Tuesday of the month at a venue in or around the Peebl

es area (check the event notices for details). These meetings run from 7.30pm until 9.00pm (or a bit later if it's clear). We also hold member viewing meetings, (at short notice because of our glorious weather.. ) at The Osprey Centre, Kailzie Gardens, Peebles EH45 9HT, using a whatsapp group to arrange and also pre arranged public viewings where folk can get help using their telescopes and we can view the sky whenever it works out weatherwise. So come along if you're in the Tweeddale area or even further afield. there's no requirement to have a telescope or any prior knowledge of astronomy, just an interest in the sky. Probably best if you bring a warm coat, hat and gloves in case we're outside for a while though! We look forward to seeing you there!

For the next month a bright comet will be visible from the UK. Comet C/2025 A6 (Lemmon) is visible both in the evening and morning sky. For the next week or so, in the evening, look above the northwest horizon west of the Big Dipper (Ursa Major). In the morning, look northwest, north of the Big Dipper.

The comet will be visible until November 12. During this time, its brightness will range between magnitude 3.8 and 4.8. To the naked eye, it will look like a faint, slightly fuzzy star; in binoculars or a small telescope, it will appear as a small hazy patch with a bright core and a short tail pointing away from the Sun.

The spectacular Perseids meteor shower, which runs between July 17 and August 24 every year, will peak on Tuesday night, August 12. This year’s shower will be spoiled by a bright, 80%-illuminated, waning gibbous moon shining all night long. While you can watch for Perseids streaking anywhere in the night sky, the time for seeing the most Perseids meteors in will be the hours before dawn on Wednesday morning, while the shower’s radiant in Perseus is high in the northeastern sky. This is the most popular shower of the year, delivering as many as 100 meteors per hour at the peak. Derived from debris dropped by Comet Swift-Tuttle, many Perseids are extremely bright and leave persistent trails. To see the most meteors during any meteor shower, find a safe, dark location with plenty of open sky, get comfortable, and just look up and around. Hiding the moon behind a tree or building will help.
