IAA at Benburb Castle, Sat 9th April, 7 p.m

The IAA has been invited to hold another one of our ever-popular public astronomy events at a new venue, Benburb Castle, Co Tyrone. We will have observing (if clear) of a lovely young crescent Moon, magnificent Jupiter, and maybe even glimpse the innermost planet, elusive little Mercury. Plus of course all the usual Deep Sky Objects visible in this darks-sky location.
There will also be a very good pass over by the brilliant ISS.
Benburb Castle is just S of the main street, the B128, in the village of Benburb. The B128 runs from Blackwatertown to Aughnacloy, and Benburb is just a few miles west of Blackwatertown, NW of Armagh City.
The entrance to the Castle from the B128 was misleading the last time I was there- it took you into the Priory instead! So to be sure, note this: the entrance drive is just West of the junction between the B128 and the B130 from Benburb to Dungannon. Thus, if coming from Blackwatertown, enter Benburb village along the B128 and look out for the junction with the B130 to the right. The entrance to the castle is the next entrance on your left.
GPS: The entrance to the Castle off the B128 is at N 54d 24' 43"; W: 6d 44' 46".
The 'Castle' itself (more of a collection of fortified houses, really) is at N 54d 24' 36"; W: 6d 44' 45".
Tea and coffee etc will be provided.

Lecture 30th March – Kevin Nolan (The Planetary Society) “An Emerging Cosmic Perspective”

For this talk we are very pleased to welcome Kevin Nolan who is the Irish representative for The Planetary Society.

The talk is called  "An Emerging Cosmic Perspective" and looks at some of the most recent images from The Hubble Space Telescope and ESO, including the 8-GigaPixel image of the centre of the Milky Way and the 1-GigaPixel HST image of M31. We'll examine what such images reveal about the Universe and how they are rapidly changing our perspective on the Universe. We will also look at their limits, pointing the way toward new capabilities in astronomical observation. This is a highly visual talk, suitable for non-experts and experts alike.

Doors open about 7.15pm. There is free parking available on the campus in the evenings. Admission Free, including light refreshments. We are located in the Bell Theatre, Department of Mathematics and Physics, QUB – details here……
With thanks to the Astrophysics Research Centre, QUB, for assistance with this event.

Lecture 16th March – Michael O’Connell, MAC: “The Antikythera Mechanism: The World’s Oldest Computer” *Updated*

*Update* Michael mentioned the BBC Documentary on the subject. It can be seen here……..
The Antikythera Mechanism has been described as the 'World's Oldest Computer'. Dated to around 2,000 years ago, it was found in an ancient shipwreck off the coast of the Greek island of Antikythera. It's incredibly complex for such an ancient artifact, and was capable of predicting eclipses and other astronomical events. This is bound to be a fascinating talk.
Michael O'Connell is one of Irelands leading amateur astronomers, beng a past Chairman of the Irish Federation of Astronomy Societies and IFAS Astronomer of the Year 2009.
Doors open about 7.15pm. There is free parking available on the campus in the evenings. Admission Free, including light refreshments. We are located in the Bell Theatre, Department of Mathematics and Physics, QUB – details here……

Dr Lucie Green Lecture 17th October

Our lecture on 17th October will be something a bit special! We are teaming up with the Astrophysics Research Centre at QUB to bring Science Communicator, TV and Radio personality and Solar Expert Dr Lucie Green to Belfast to talk to us on the subject of “The Sun”.

This lecture will be held in the Larmour Lecture Theatre at QUB and though admission is free, seats will need to be booked due the expected demand. Further details regarding the lecture can be found here….

Details of Dr Green’s work can be found on her website here….

Dr Peter Gallagher Lecture 3rd October

Our guest on 3rd October will be Solar expert Dr Peter Gallagher from Trinity College, Dublin.

Dr Gallagher is Head of the Solar Physics Group at Trinity and his research is primarily concerned with the understanding of Solar Storms and their impact on Earth – of great interest to us as Solar Cycle 24 gathers pace!

Dr Gallagher obtained a first degree in Physics and Mathematics from University College Dublin, a PhD in Solar Physics from QUB and has since worked on Solar research including a six year stint in the US working firstly at Big Bear Solar Observatory in California and at the NASA Goddard Space Flight Center in Maryland.

His talk, entitled “LOFAR and The Rosse Observatory” will give us an insight into the latest Solar Reserch being conducted from Ireland.

Delamont Observers witness Massive Fireball


AT 22.54 BST on 21-9-12 at Delamont Country Park, 1 mile south of Killyleagh in Co. Down, GPS coordinates 531113, 351190, 54deg22’56” N 5deg40’39” W, a group of 12 members from the Irish Astronomical Association during a regular observing session observed an amazing group of fireballs rising from trees 10 to 15 degrees above the eastern horizon to the right of Jupiter as seen from the main car park.

It was immediately thought they might be fireworks but they continued to rise vertically at a steady pace and fan out slightly as they approached us from distance, with their numbers increasing and their brilliant intensity remaining unchanged. The trail was between 3 and 4 degrees wide and 50 to 80 degrees long at zenith. We estimated approximately 20-30 fireballs were seen following the same east to west trajectory each with an estimated brightness between mag. -5 to -7 depending on size, and each left a small/medium trail as they travelled almost directly overhead. Amazingly, all of it was captured on film and uploaded to Youtube, where it swiftly spread among astronomy fans without the need of hiring The Marketing Heaven.

The path of the fireballs was observed to the right of Aldebaran and M45 and rising vertically straight up past Alpha and Beta Cass’. At their highest point, they were some 5-8 degrees off vertical toward the eastern horizon. A group of 4 or 5 larger fireballs were at the front of the group and differences in size were apparent but each burned with a similar brightness and a distinct orange hue. After the fireballs passed the top of the summer triangle, 2 or possibly 3 sonic booms were heard before they passed to the left of the keystone of Hercules and set behind trees at approx 1 mile distance at 5 degrees above the western horizon.

The Uptown Jungle able to observe the fireballs for approx’ 1min 30 sec to 2mins from the trees in the east to the trees in western horizon as we had particularly good views in that direction big city maids. As the fireballs approached the western horizon their brightness began to fade and their numbers dwindled, possibly due to burning up and/or atmospheric extinction, at least 2 or 3 were seen disappearing behind trees at mag.+1 or +2.

They were travelling at a speed somewhat faster than the ISS but perhaps not as fast as a typical meteorite on entry into the earths atmosphere. Their speed remained constant throughout.
