MOONWATCH – Friday May 5th

The next public observing event being held by the Society is a “MoonWatch”, at the Brewery Arts Centre this coming Friday May 5th, starting at 8pm. Members of the EAS will have telescopes set up in the gardens of the Brewery Arts Centre to show people the Moon. which will be shining close to Jupiter that evening.

The event is free, and members of the public are invited to bring along their own equipment – cameras, binoculars and telescopes – to join in the fun!

EAS TRIP TO ALSTON OBSERVATORY

On Monday night around a dozen members of the Eddington AS travelled down to Alston Observatory, near Preston, for a very enjoyable evening spent listening to a talk on our place in the universe, looking at a lovely old “vintage” telescope and looking through a superb 28″ telescope! Full report at the next meeting, with lots of photos. In the meantime, thanks to everyone who came along, and a special thanks to David Glass for arranging the evening for us!

 

March Observing Evening

About a dozen EAS enthusiasts turned out on Thursday for what will probably be the last observing evening of this season.  A little haze high in the sky meant that there was a slight background wash making faint objects more challenging, but we still bagged a good set of observations.  

Orion offered final views of M42 (The Orion Nebula) nebula setting in the west, and we also took a long look at Betelgeuse (Alpha Orinonis) while observing individual stars including Procyon (Alpha Canis Minoris), Castor (Alpha Geminorum) – a double separated by 90 light years or 5 arcsec viewed from Earth – and Pollox (Beta Geminorum).  

Open clusters were a feature of the evening, M35 in Gemini, M36 (“The Pinwheel”), M37 and M38 (“The Starfish”) in Auriga and M44 (“The Beehive”) in Cancer.

Galaxies M65 and M66, two of the “Leo Triplet”, were just visible in Leo, as were M81 and M82 in Ursa Major.

Comet 41P/Tuttle-Giacobini-Kresák was seen as a very challenging fuzzy spot in my 115mm refractor, as was nearby M97 (The Owl Nebula) used for comparison.

We finished with pretty good views of Jupiter and the four Gallilean moons Io, Europa, Ganymede and Callisto.

My sincere thanks go to all members who come and make these sessions a success. There is still room for improvement and I look forward to canvassing members’ views over the next few EAS meetings to see how we can make then even better.

Observing Iridium

Apologies to last night’s observers for predicting the two iridium satellites that failed to appear. Still not sure why but most probably the low angle, 16°. I ‘mistook’ on the direction – it was NE not NNE but you would have thought that was near enough for a -2.8 mag.

EAS TRIP – April 24th

Everyone,

For those who weren’t at the March meeting – or who were but would like a reminder of the details – here’s some information about our Trip being planned for the evening of April 24th. Many thanks to Richard Rae for organising this. If you’re interested in going, please pass that interest on at the April meeting.

 

EDDINGTON AS MoonWatch This Friday

Cross your fingers for clear skies this coming Friday night (March 3rd) because we are having another of our hugely popular “Moon Watch” nights at the Brewery Arts Centre!

As I write this the weather forecast isn’t very good, but as we all know they can change overnight, or just be plain wrong, so let’s just wait and see what happens. If you can see the Moon at or after 6.30pm on Friday night come down to the Brewery, where we’ll have our telescopes set out in the garden.

And what will you see? Well, the Moon will be just short of First Quarter, which is the very best time to look at it through a telescope (not Full Moon, as everyone seems to think) because that’s when the Moon’s jagged mountains and deep craters stand out from the surface most clearly.

On Friday night we’ll have a spectacular view of some of the Moon’s most famous features – weather permitting!

If you come good and early, before Venus drops behind the trees, we should also be able to show you the “Evening Star” through our telescopes – which is now looking like a beautiful thin crescent through telescopes – and the planets Mars and Uranus too, although they’ll just look like tiny stars.

Unfortunately the Space Station won’t be putting in an appearance during our MoonWatch, it’s not an evening object at the moment, but we should see a few other satellites drifting across the sky while we’re Moon-gazing.

The event is free, begins at 6.30pm, and will end around 9pm.

An eclipse and a comet this weekend…

There’s a lunar eclipse happening tonight, which lasts through until the early hours of tomorrow morning, and it’s attracting a lot of media attention. Unfortunately, much of the media coverage is at best misleading and at worst totally wrong. The eclipse happening tonight is a ‘penumbral’ eclipse, which occurs when the Moon drifts through the outer part of the Earth’s shadow. This part is much less dense than the central part of the shadow, the ‘umbra’, so instead of going orange, like it does during a classic total lunar eclipse, the Full Moon will just darken… a bit… and appear more greyish than usual, especially at the top. It’s still well worth watching, because every eclipse has its own appeal, and many astronomers and skywatchers think that the appeal of a penumbral eclipse *is* its subtlety. If you go out to watch it, as long as you don’t expect to see a tangerine- or a Hallowe’en pumpkin lantern-like Moon hanging in the sky, you’ll enjoy it.
 
The media is also telling everyone how a comet is going to “whoosh” or “zoom” across the sky on Saturday night, and are illustrating their pieces with dramatic photos showing comets from the past with bright heads and long, glowing tails. The truth is rather different. Comet 45P is not going to whoosh or zoom across the sky – in fact, it’s been in the sky for ages already, moving across it slowly, like all comets do. It’s just closest to us on Saturday night, that’s all. And those photos are all wrong because the comet is very small and very faint, far too small and faint for the naked eye to pick up on a dark night – and the nights won’t *be* dark this weekend because a big, bright Full Moon will be drowning out everything else in it! If you know the sky well, and have a chart or map showing where the comet is you MIGHT pick it up with binoculars or a small telescope, but it will be, as they say, “challenging”..!
 
Don’t be put off looking for the comet and the eclipse. They’re definitely happening – just not in the way much of the media is reporting s breathlessly.
 
If you want any more info, feel free to ask! In the meantime, here’s a chart showing the times of the different stages of tonight’s eclipse, which we hope you find useful…
Note:  the eclipse will be at its best at around half last twelve.
