Lecture 4th February 2015 – Tom O’Donoghue -“Astrophotography: From Single Pane to Mega-mosaic”

Tom O'Donoghue takes some of the best deep sky astrophotos you will ever see taken by any amateur astronomer. He is totally dedicated, to get the best quality images possible! As well as taking the superb shots you can see on his website www.astrophotography.ie he is now working on a 'mega-mosaic' of the whole Orion constellation and all its associated nebulosity, of which the best known are of course the Orion Nebula itself (M42), the 'Running Man Nebula', and the Horsehead Nebula. But there's much more!
 
In this talk he will describe how he acquired his skills and his equipment, how he takes and processes the images, and describe his "Orion Mega-Mosaic"
 
The lecture is free and open to all, including free refreshments. Venue: Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.

Lecture 21st January 2015 – Professor Alan Fitzsimmons – “Rosetta at Comet 67P/Churyumov-Gerasimenko”

Synposis: This year the European spacecraft Rosetta became the first spacecraft to rendezvous with a comet, and the first to place a lander on its surface. The 3-day landing and operations period of the Philae lander was followed by millions of people around the world. Yet we still have at least a year of stunning science to come from Rosetta – plus hopefully some more from Philae. This talk will summarise the aims of the mission, show some of the first results, and explain some of what will happen in the coming months.

Lecture 7th January 2015 – John Flannery (IAS) – “The Sky by Eye – How to Rediscover the Soul of Astronomy”

Arthur C. Clarke once described the Universe as a device contrived for the perpetual astonishment of astronomers. Anyone can discover that sense of wonder. You just have to look up. It’s a common belief you need some form of optical equipment to witness those astonishing sights but that is not the case.

The Sky by Eye is a list that encourages people to observe the Universe with the unaided eye. It comprises 110 sky objects and phenomena ranging from the whimsical to challenging. Examples include studying the colours of the Moon, tracking a planet through its opposition loop, using a UHC filter to observe deep-sky objects with the unaided eye, observing the broad spectrum of atmospheric optics, and even building medieval astronomical instruments. 

The beauty of the Sky by Eye list is that you can delve deeper into areas such as meteor observing or revisit some aspects as your awareness grows. You may take a lifetime to tick off all the sights but the goal is to open your eyes to understanding and appreciating the rhythms of the sky, as well as build a foundation to enhance your enjoyment of astronomy. The list draws on the work of others including Joe Orman, Fred Schaaf, and Chet Raymo who all touch the soul of why we are naturalists of the night.

The lecture is free and open to all, including free refreshments. Venue: the Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.

Naked Eye Comet C/2014 Q2 Lovejoy visible from Ireland!

A new comet discovered by Terry Lovejoy (his 5th!), official name C/2014 Q2, is heading North and has gradually brightened. Currently it shines at magnitude 5.5, barely visible with the unaided eye even in a very dark sky, but relatively easy in binoculars.

IAA member John C McConnell has imaged the comet – shown here, taken with a 50mm lens at f2.2 for 10 seconds.

IAA Lecture 17th December: Dr Ernst de Mooij (QUB) – “Characterising the atmospheres of exoplanets”

Over the past two decades more than one thousand planets have been discovered outside our Solar System. What is even more interesting is that we have started to investigate atmospheres of these planets using telescopes both on the ground and in space. In this talk I will show how we can study the atmospheres of these alien worlds, and what we have learned from these observations.

 
The lecture is free and open to all, including free refreshments. Venue: the Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.

Lecture 3rd December: Prof Tom Ray, of the Dublin Institute for Advanced Studies. Title: “The Einstein Lens and a Tale of Two Eclipses.”

This lecture will present some exclusive new findings about the trips that were made to various parts of the world to observe the Total Solar Eclipse in 1919: the first attempt to check the predictions of General Relativity. see http://www.earthmagazine.org/article/benchmarks-solar-eclipse-proves-relativity
 
There are two important local connections –
 
1. The telescope lens, which was made in Ireland; and 2. The astronomer who led the expedition to Brazil was Andrew Crommelin, born in Cushendun, Co Antrim, and son of the family who gave their name to NewtownCrommelin in Co Antrim! See http://www.newulsterbiography.co.uk/index.php/home/viewPerson/1805  Andrew Crommelin was a noted cometary astronomer, and one of only 4 people who have a comet named after them although they did not discover it: http://en.wikipedia.org/wiki/27P/Crommelin
 
You will have a chance to see the telescope lens that proved Einstein’s theory of Relativity was correct! And it was made in this Island!
 
   
This lecture will as usual be in the Bell Lecture theatre, Physics building, main QUB Campus.
 
The lecture is free and open to all, including free refreshments. Venue: the Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.

IAA 40th Anniversary Dinner – Friday 28th November

To celebrate the 40th anniversary of the formation of the IAA (formerly the Belfast Centre of the Irish Astronomical Society) in 1974, we are having a Celebratory / Seasonal Dinner on Friday 28 November, in a private suite in the Maynard Sinclair Pavilion, Upper Newtownards Road, Stormont, Belfast. We have got an excellent deal on this so it's not to be missed!
 
There is free parking at the venue. Directions to venue will be given later
 
As well as the meal, we will have some light-hearted fun, including an after-dinner address by one of the top astronomers in the country, Prof Alan Fitzsimmons of QUB: this will be not so much about astronomy, as all the interesting, embarrassing and hilarious things that happen in the background when pursuing a career as a top professional observational astronomer. 
 
There will also be a ‘rogues gallery’ of photos and memorabilia of various member and events over the years – you might find yourself in the ‘Most Wanted’ section. Plus a fun quiz with spot prizes!
 
We hope to get a really good attendance at this event, which is open to partners and friends too if you wish.
 
If you wish to attend this event, please complete and return the form available here…….

IAA Lecture, 19th November, Dr Mike Simms – “What meteorites tell us about the early Solar System”

How can we determine the age of a meteorite, or even the Solar System? How can we unravel the processes that formed Earth and the rest of the Solar System from the primordial dust cloud? The presence, or absence, of particular elements and isotopes in meteorites and their components, and the physics and chemistry of those elements, provides abundant clues to what happened in those first few million years.

Ulster Museum Palaeontologist Dr Mike Simms is also one of the UK's foremost experts on meteorites and will explain all in this lecture which is bound to provide a fascinating account of what we can learn from rocks from space!

This lecture will as usual be in the Bell Lecture theatre, Physics building, main QUB Campus.
 
The lecture is free and open to all, including free refreshments. Venue: the Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.

Huge Fireball over Ireland and Scotland

At 17:30 on Tuesday 18th November IAA President Terry Moseley received a call from an IAA member at the Met Office in Aldergrove reporting a fireball "as bright as the Moon". The still frame above was taken from Low Craighead Farm, near Girvan, Ayrshire (please contact us if this is yours!) and shows the fireball, and to the right of it, Altair, a first magnitude star, the 12th brightest in the sky!
 
Terry was on to the BBC who carried the report on Evening Extra on Radio Ulster, and on the BBC NI News website here…. 
 
Eye-witness reports came flooding in with over 40 being received from as far afield as Dublin, North West England and Western Scotland, and some video footage was sent to Armagh Observatory from Girvan, Ayrshire.
 
The reports are being evaluated and responded to, but this looks very interesting indeed! 
 
Here is the first report from Donald Ferguson at the Met Office, Aldergrove….
 
Fireball sighting.
 
Time 17:27 and approx 15 secs. Watch checked against online clock.
 
Looking NE, from Aldergrove, very bright, fireball observed, head was brilliant white with a touch of pale turquoise in it and there seemed to be a translucent ‘tail’ of dark orange/brown behind, so I had to do a double take to ensure that is wasn’t a firework. Magnitude approx -9 or -10, so brighter than Iridium satellites at their best and about 4 times the size. The head also seemed to be quite elongated and pointed in an ellipse shape.
 
I saw it heading down towards the horizon at an angle of approx 15-20 deg, from a compass bearing of 070 deg to 030 deg, and lasting for approx 5 seconds. It disappeared steadily, without a flash, just getting smaller and smaller, and the last I saw of it was at a compass bearing of 030 deg, and lower than in the sky than Cappella was at the time.
There was no audible sound with it.
 
There were 4 witnesses, including myself and we all agree this is a fair assessment of events.
 
Hope that helps,
