Hi all,

ƒŠ

1.ƒŠ TheƒŠnext Irish Astronomical AssociationƒŠMeetingƒŠ will be on WedƒŠ15 December, in the Bell Lecture Theatre, QUB. It will beƒŠa Hands-on Telescopes + Bring & Buy event"ƒŠ.

We will have a large variety of telescopes, binoculars, & other astronomical equipment on display for you to examine and compare, and there will be a series of short presentations on various aspects of choosing and using astronomical equipment. There may even be some bargains on sale from North Down Telescopes.

ƒŠƒŠ As well as that, there will be a Bring & Buy session, where you can sell or swap your surplus or unwanted gear for something else which tickles your fancy. There will also beƒŠsome great bargains in astronomical & spaceƒŠbooks as well, and probably videos & DVDs too.

ƒŠƒŠ Note: this is not a commercial operation on behalf of the IAA, but a 'service to members and friends' to enable them to get the most suitable equipment to pursue their hobby.

ƒŠ Time: 7.30 p.m. Venue: Bell Lecture Theatre, main Physics Building, Queen's University, Belfast. Free parking is available on the main campus, right beside the lecture theatre, from 5.30 pm onwards. Admission free, including light refreshments: All are welcome. See www.irishastro.org for full details of the programme.

2. ISS MORNING PASSES. A series of morning passes of the ISSƒŠcontinues for a few more daysƒŠâÀÓ get detailed predictions for your location from www.heavens-above.com

3. GEMINID METEORS. The annual Geminid meteor shower, which peaks on the early morning of 14 December,ƒŠis usually the best of the year, with about 100 meteors per hour under ideal conditions. But this year the 8 day old Moon will interfere with observingƒŠduring the first part of the night of the 13th/14th, as its light will drown out the fainter meteors. It will set at about 12.30 for most observers in Ireland, before the maximum of the shower, so wrap up EXTRA well for a late session to be rewarded with aƒŠview of one of the year's best free sky shows.

ƒŠƒŠ The radiant lies just above Castor (Alpha Gem). Geminids are moderately slow meteors, and there's a reasonable proportion of bright meteors, making this one of the best showers for photography or video.

ƒŠƒŠ As for all meteor showers, you'll get best results in a really dark sky, away from all sources of light pollution. Allow about 5 minutes for your eyes to dark adapt after exposure to white light, but note that full dark adaptation takes 20 - 30 minutes! So use a red torch for setting up, checking your camera, getting a cup of coffee etc.

ƒŠƒŠ Aim your camera about 40 - 50 degrees from the radiant, and about 50 degrees above the horizon, to maximise your chances of recording a meteor. You'll have to experiment to see how long an exposure you can give before the image starts to 'fog' due to background sky brightness. Also beware of dew forming on the lens. And bring spare batteries - the cold temperatures will shorten the life of those in the camera; keep the spare ones warm in a pocket to get the best out of them.

ƒŠƒŠ (You may have seen in the news reports of a very bright fireball seen over GB from Somerset to South Scotland on Wed 11th Dec. Many astronomy commentators described it as an 'early Geminid'. Until we know the exact trajectory, that remains to be established. It's possible, although the Geminid radiant was just about on the horizon at the time of the fireball (17.38 UT). But ignore the other comments that the Geminid meteor shower will coincide with the Total Lunar Eclipse (see below), as the shower ends on Dec 16!)

4. METEOR OBSERVING AT ARMAGH OBSERVATORY
The Armagh Observatory is opening its doors at 8.00pm on Monday 13th December for an evening of meteor observing to capture the Geminid meteor shower. ƒŠIf you've never seen a meteor or shooting star, this is the perfect opportunity to learn what they are and, if it is clear, to see some of these celestial fireworks for yourself.
ƒŠƒŠ The open evening will begin at 8.00pm at the Armagh Observatory. ƒŠIf it is clear, there will be a short introduction to the sky and the starsƒŠand planets, and instruction on how best to observe meteors. ƒŠIf it is cloudy there will be short talks on astronomy and an opportunity to meet the astronomers and find answers to questions about meteors or any other aspect of astronomy. ƒŠAnyone wishing to join this event is requested to telephone or send an e-mail to Mrs Aileen McKee at the Armagh Observatory, College Hill, Armagh; Tel: 028-3752-2928; e-mail: ambnarm.ac.uk, and to be at the Observatory shortly before 8.00pm.
ƒŠƒŠ For meteor observing, the main rules are always the same: find a place as far as possible from light pollution or the interfering light of the moon; wrap up well against the freezing cold; and make yourself comfortable, ready to catch the meteors when they appear.

5. DRAKE EQUATION TV SPECIAL, 14 December:

In a 1hr special, produced in partnership with the BBC, Bang Goes The TheoryâÀÙs Dallas Campbell goes on a world wide journey to discover how one of the most controversial formulae in science âÀÓ the Drake Equation âÀÓ is changing our view of life, the universe and our place within it.
ƒŠƒŠ In 1961 Frank Drake took everything he knew about star formation, planetary systems, the evolution of biology and the life cycle of civilisations; and from this jumble of science he formulated one of the most seminal equations in the history of science. It came to be known as the Drake Equation.
ƒŠƒŠ For many years, our place in the universe was the subject of theologians and philosophers, not scientists. But DrakeâÀÙs Equation gave scientific credibility to the possibility of extra terrestrial life.
ƒŠƒŠ At the time, Dr Frank Drake was one of the leading lights in the new science of Radio Astronomy when he did something that was not only revolutionary but could have cost him his career. Working at the National Radio Astronomy Observatory in Greenback in Virginia, he pointed one of their brand new 25mtr radio telescopes at a star called Tau Ceti 12 light years from Earth. His mission, to listen for signs of extra terrestrial intelligence âÀÓ quite literally to listen for ET talking.
ƒŠƒŠ Examining seven key elements necessary for extra terrestrial intelligence to exist; from the formation of stars to the likely length a given intelligent civilisation may survive. When Frank and his colleagues entered the figures, the equation suggested there was a staggering 50,000 civilisations capable of communicating across the galaxy at this very moment.
ƒŠƒŠ But in the 50 years of listening that has followed, not one single bleep has been heard from ET. So were Drake and his followers wrong? Is there no life form out there capable of communicating? No one is really sure as the search itself is so difficult. DrakeâÀÙs own calculations are that weâÀÙd have to scan the entire radio spectrum of 100.00000 stars to be sure of contact.
ƒŠƒŠ Dr Dave Rothery, Senior Lecturer at The Open University and academic consultant for this programme, says: âÀÜWhat the equation and the search for life has done is focus science on some of the other questions about life in the universe âÀÓ specifically biogenesis, the development of multi-cellular life and the development of intelligence itself.
ƒŠƒŠƒŠ âÀÜThe answers to those questions are increasingly suggesting that, far from being a one off, are increasingly suggesting that, far from being a one off, life may not only be common in the universe by once started will lead inevitably towards intelligent life.âÀÝ
ƒŠƒŠ The Drake Equation is a 1hr special for BBC4 to be broadcast at 8.00pm on 14 December. (Scheduling subject to change, please check TV listings.)

6. TOTAL LUNAR ECLIPSE, 21 December. Don't forget to book an early morning wake-up call for the morning of the winter solstice, when there will be a Total Lunar Eclipse, visible from all over Ireland, just before dawn. I'll have all the details for the main locations all over Ireland in the next bulletin.

7. Evert Meurs retires:ƒŠ Professor Evert Meurs has retired from the Dublin Institute for Advanced Studies with effect from the first of this month.ƒŠ I am sure that we all wish him a happy and productive retirement and look forward to his continued involvement with astronomy in Ireland.ƒŠƒŠ The Governing Board of the School [of cosmic physics]ƒŠis anxious that every effort be made to fill the resulting vacancy [Senior Professor of Astronomy]ƒŠand to this end will be inviting expressions of interest from suitably qualified individuals by the end of this year with a view to forwarding a nomination to Government as soon as possible.ƒŠƒŠ Full details of the application processƒŠare on the DIAS web site http://www.dias.ie/lang/en/commun/vacancy_Astro.htmlƒŠand an advertisement will appear in Nature this week. [From Dr Neal Trappe, ASGI].
ƒŠƒŠ (I hope that the appointment willƒŠalso fill the now vacant post of Director of Dunsink Observatory - it would be a real shame if that position were to be closed, after a period of 225 years! T.M.)
