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.

The battle is over. (for now!)

I had a call last week from Amey, following my complaint on 9th January about the new street light that pours the light of a thousand suns into my garden. A man came round tonight.

I had replied to their response and then heard nothing. for four weeks. I emailed again and got no response, so I threatened them with going to my counsellor. They said they couldn't trace all my previous correspondence. I sent it all to them and waited. I got the call whilst in Lanzarote last Friday.

I set up my scope and mount in the dining room and deliberately invited the man in whilst I put my shoes on. I'd also taken the waiting time as an opportunity to sort out my astro gear, so there was a lot of stuff around the place when he walked in.

We walked outside and he pointed to the bright white streetlight across the road and said, "Yeah, we'll put a shade over it for you."

No argument no bluster, no discussions and no reason to grab him round the throat and throttle him! He pointed to the other light, that hasn't been connected yet. "I'm not sure if there's anything that can be done about that one as it's at an angle, so a shade on the front might not help." he said. I pointed to the previous light that has been shaded, and said, "That's at an angle, and it's MUCH improved!" He conceded that and then went on to say it couldn't be dealt with until it was connected. Fair point, I suppose.

So, I win round two. I just have to wait until the shade gets fixed and then complain again when light number three goes live.

Someone asked at our meeting yesterday evening about which stars made the 'winter circle'. Betelgeuse is approximately at the centre; I have annotated this image with the names of the stars that make this 'circle'

Cropped from one of the shots of Mercury that I captured recently (Mercury was 68 % illuminated that evening). I guess the colours must be due to the atmospheric conditions that evening as I did not use a refractor on any other lens; my images were captured using a Canon EOS 60D mounted at prime focus onto a Skywatcher 200 reflector telescope.

Comet C/2017 E4 Lovejoy with its nice tail, just imaged by Tenagra Observatories & The Virtual Telescope Project. It is much brighter than our past observations, a few days ago.

Aldebaran Occultation, 28th April


I've not found Sheffield on the list but ....

Occultation predictions of 692SK5 Magnitude 0.9
Date 2017 Apr 28

Moon: % illumination = 7+, Solar elongation = 32

U.T. Sun Moon CA PA WA a b
Location h m s Alt Alt Az o o o m/o m/o

739 GB Manchester 18 9 4 11 32 254 57N 58 66 +0.8 -0.4
728 GB Leeds 18 9 19 11 32 254 55N 56 64 +0.8 -0.4
749 GB Nottingham 18 10 10 10 32 255 58N 59 67 +0.7 -0.5

(formatting may be device-dependent)

Occurs just after 6 pm with the Sun 11 degrees high in the sky. Moon at 32 degrees and 32 degrees from the Sun. 7% illuminated Moon.

So, in daylight sky which will cause challenge.

Re-appearance times given further down ....

Note that the list also includes

715 GB Golouchestershire 18 9 51 11 33 255 61N 62 70 +0.8 -0.5

Two photos of Jupiter plus Europa (left) and Io, Ganymede, Callisto (right) taken at 2128 and 0008 on Mar 25/26. 160 minutes apart so disappointing that there is no apparent movement. Io and Europa both around their maximum elongations, Ganymede going out slowly and Callisto coming in slowly.

A short time-lapse that I made showing movement of this comet (and my scope mount!) using some of the data that I captured yesterday.

"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 πŸ™

Looks like we're going to be clouded out so we won't be at the Sportsman this evening. Sorry folks. πŸ™

Weather has beaten us again. Forecast is poor and the ground at the Sportsman will be swampy. Sorry folks but no stargazing this evening.
