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,
 
Regards
 
 

IAA Lecture 5th November – Prof Andy Shearer: “Feeding the giant – science possibilities of the next generation of extremely large telescopes.”

Synopsis: "Over the next ten years a number of new giant telescopes will come on line – these include the European Extremely Large Telescope (E-ELT), the Square Kilometre Array (SKA) and in X-rays, Athena. Each one of these will dramatically change our view of the universe. At a recent workshop in Galway, "Speed and Sensitivity: Expanding Astronomical Horizons with ELTs" the possibilities from the current generation of instruments as well as the next generation of instruments for ELTs were discussed. This talk will look at what science is possible with ELTs and what questions will be addressed and hopefully answered by ELTs."

Some of the new horizons being opened up by these developments are mind-blowing, so this will be a fascinating talk.

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.

World Space Week – Elements of the Universe, Ulster Museum 11th October

The IAA will be running a major public astronomy & space outreach event in conjunction with the Ulster Museum on Saturday 11th October.

This will be at the Museum on Stranmillis Road, from 11:00 to 16:30.

This will comprise:
Starshows with a space theme in the ever-popular Stardome (courtesy of Armagh Planetarium) at 45 minute intervals starting at 11.00.

Solar observing from the Museum forecourt, weather permitting. We will have various special safe solar telescopes to show incredible views of our nearest star, which still poses many puzzles for astronomers.

If it's cloudy, we'll have the telescopes indoors as part of our major exhibition.

Exhibition: all things astronomical and space will be on display, including meteorites which are actual rocks from space, and various items of space memorabilia

Meet our own 'Ulsternaut', Derek Heatly from Groomsport, who will be the first person from N. Ireland, if not all Ireland, to fly into space with Virgin Galactic.

Ask a question about astronomy or space – our Experts will be there to try to answer them.

IAA World Space Week Lecture, 8th October: Prof Don Kurtz, UCLAN: “The Kepler Mission: Exoplanets and Asteroseismology”

Prof Kurtz is a very highly regarded speaker on a wide variety of topics, and this one for World Space Week will focus on one of the most successful space missions ever: the Kepler Spacecraft. This has now detected well over 1,000 planets going round other stars, some of which are like planets in our own solar system, including a few which are fairly like Earth, and some which are amazingly different from our own familiar ones.

The spacecraft's detectors are so sensitive that they can even detect 'starquakes' on distant stars. Come along and be amazed at the fantastic findings from this space mission.

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 New Season Opening Lecture 24th Sept: Latest Science Results from Rosetta, by Leo Enright

The Rosetta spacecraft is now in a sort of ‘orbit’ round Comet Churyumov-Gerasimenko, sending back some jawdropping photos. After studying the ‘binary’ surface in more detail, it will land a probe on the surface. 
 
This talk by Ireland’s leading science broadcaster and journalist, will reveal the latest findings from the fantastic Rosetta spacecraft at Comet C-G. As you can see from some of the images at NASA Science here…, the comet is weird – absolutely unlike anything we’ve seen before. And Leo usually updates his talk from the Internet just about 10 minutes before he’s due to start, freexxx4u.com so it will be the VERY latest information. Not to be missed!
 
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.

The Noctilucent Cloud Season begins

From around the end of May until the beginning of August these mysterious white clouds can be seen from Northern latitudes. As luck would have it, Northern Ireland is ideally placed for observing these clouds – further north and the sky is too light, further south and the clouds are too close to the horizon to be seen, although in recent years there have been sightings from Southern England.

Last year (2013) the first sightings occurred on 15th May which is unusually early, and there was a spectacular display on 31st May – see images from IAA members here…. This year however the first sightings occurred on 24th May which is more normal. We can expect several display over the next two months. In order to spot them you'll need to be looking towards where the Sun would be if it wasn't 6-16degrees below the horizon, so starting in the NW about 30mins after sunset to NE 30 mins before dawn.

In order to photograph these clouds you'll need a camera capable of exposures of a few seconds and a tripod or other support. Focus to infinity and try exposures of 5-10 seconds with the lens wide open and ISO 400-800 then adjust around this depending on how bright the image are coming out on your screen.

If you get any images, send them in!

Good luck!

IAA President receives BEM Medal

The hot news of last Summer was that Terry Moseley, now commencing his 10th year as IAA President, had been awarded the British Empire Medal for services to Astronomy Education. Well, he has now received his medal and here is Terry's own account of his day…..
 
"Although the announcement of my award of the British Empire Medal was in June 2013, I was not able to attend that Autumn's Hillsborough Presentation Ceremony as I had already booked to go to the RAS Commemoration for Sir P. M. at the NSC in Leicester. The next one was on April 30 just past, so my guests Angela O'Connell, son Kevin & daughter Katie accompanied me..
 
  
The presentations are made by the Queen's Representative for each county, the Lord Lieutenant: for Co Antrim that's Joan Christie, DL, OBE. Incidentally, it was she, representing the Monarch, who officially welcomed President Obama & family when he landed at Aldergrove for the G8 summit last year. So I've shaken hands with someone who has shaken hands with the Obamas! The official photos are not available yet.
 
After the formal ceremony there were light refreshments, and a chance to explore the lovely gardens. Incidentally, as far as I could tell, the sundial is not aligned properly!
 
Next is the trip to Buckingham Palace for the Queen's Garden Party on June 3. Only one guest is allowed for that, so Angela will be doing the honours."
 
So, Congratulations Terry from all of us in the IAA!

North Down Museum – Stars and Mars, Moon and Jupiter!

The Irish Astronomical Association will be holding another of our very popular astronomy evenings at the North Down Museum beside Bangor Castle, on Saturday evening, 3rd May, at 6 pm. Once again we'll have a selection of powerful telescopes and binoculars for viewing the night sky, an exhibition, short astronomy and space films, a selection of meteorites (rocks from space) which you can actually hold, and of course the Stardome mobile planetarium just in case of bad weather. And you'll have a chance to meet our own 'Ulsternaut', Derek Heatly from Groomsport, who is booked to fly into space with Virgin Galactic.
 
 
There will be free shows in the Stardome at 6:15, 7:00, 7:45, 8:30 and 9:15, and these must be booked on the night.
 
The highlights in the sky will be a spectacular crescent Moon high in the sky, observable in the daylight – sunset is at 9pm. In addition as soon as darkness fallswe will get a great view of giant Jupiter, the largest planet in the Solar System, with its four large Moons, and a bright Mars, of course this depends on the weather!
