Sheffield Astronomical Society

The Sheffield Astronomical Society has around 100 members and serves Sheffield, South Yorkshire and North Derbyshire. The society holds several meetings each month including observational sessions of the sun and the night sky. Sungazing sessions are held between the months of April and August in the Sheffield Botanical Gardens, where we use a variety of specialist equipment to view the sun in complete safety. Using this equipment, members of the public can see sunspots, prominences, solar flares and other features of our star. Sungazing sessions start at 12:00 and run until 16:00. Stargazing sessions are held between the months of September and March at The Sportsman Inn on Redmires Road. Using the society telescopes, members of the public can join us in viewing stars, galaxies, nebulae, open and globular clusters and the moons and planets of the solar system. Stargazing sessions start at 19:30 and can last into the early hours if the skies are clear. Both stargazing and sungazing sessions are very dependant upon our changeble British weather, so please observe the facebook group or call the SAS hotline on 7852 298 612 if you are unsure. Beginner's Evenings are speaking events held at the Ranmoor Parish Centre where society members present on various astronomical phenomenon. Speaker's Evenings are speaking events also held at the Ranmoor Parish Centre where an external speaker from the astronomical community is invited to deliver a presentation. Speaking events start at 19:45 and run until no later than 22:00. This is an open Facebook group with little moderation and we would like it to stay that way. Please post responsibly. Spamming will not be tolerated.

Hello, been looking at this light pollution visualisation with a view to finding the nearest 'reasonable' dark site: https://www.lightpollutionmap.info/#zoom=12&lat=7060192&lon=-182416&layers=B0TFFFFFFF - I'm up at Wadsley (near Loxley), anyone know of any good sites to pitch near Bradfield?

Pictures of the Sun taken Saturday (mid-morning), Sunday (lunchtime) and then Monday early morning. It's possible to find a sunspot and see its progress across the disk. On the middle image, there is a foreground object (or some kind of flaw) near the bottom. I noticed it in slightly different positions on a few photos taken within a minute or two.

Here it is an animation of comet C/2015 ER61 and its "b" fragment we spotted yesterday. As you will see, there were also other observations from other observers. We are happy!

"If you want to teach effectively, one of the things you have to do is grab people's attention." Dr Ed Daw is a Reader/Lecturer in Physics at the University of Sheffield. Ed was part of a team that confirmed the existence of gravitational waves, 100 years after Einstein’s prediction, heralding a new frontier in astrophysics and cosmology. Here he explains how his love of the blues influences the way he teaches. #MotivationalMonday

Unlikely to be any stars this evening at the Sportsman Inn, so we're cancelling tonight and trying again next week. Sorry folks 🙁
18/02/2017 at 7:43am
Looks like we're going to be clouded out so we won't be at the Sportsman this evening. Sorry folks. 🙁
12/11/2016 at 8:53am
Weather has beaten us again. Forecast is poor and the ground at the Sportsman will be swampy. Sorry folks but no stargazing this evening.
