Venus Transit 6th June


The last chance until 2117 to see a Transit of the planet Venus - where Venus passes in front of the Sun - takes place on 6th June. The most favoured locations are Eastern Asia, Australia and New Zealand, but it is possible to see the some of the event from Ireland. However the choice of time and location is crucial, and Terry Moseley has put together an excellent article explaining the choices here....

Weather permitting there will be an IAA Public Viewing Event on the East Antrim coast - Terry has reconnoitred a number of sites considering a number of factors including visibility, accessibility and car parking and we have chosen Garron Point on the Antrim Coast Road as offering the best opportunity of any site on the Island of Ireland.

In the event of Sea Fog, always a possibility on this coast, a secondary site has been chosen at Ballycoose - aka Knock Dhu or the car park on the Feystown Road above Cairncastle. The sunrise is apparently just visible from this site if we use the southerly end of the car park for observing, and offers an elevation of 270m though the duration of visibility is some seconds shorter than Garron Point.

Note that even though the Sun will be low in the sky, the usual precautions still need to be observed - Never view the Sun directly with the naked eye or with any unfiltered optical device, such as binoculars or a telescope!

See here for safe viewing options....

Maps to the two sites are shown below - keep an eye on the forum for any last minute changes - all are welcome - we will assemble from 0430 BST onwards.

There is more information on the Transit on the Transit of Venus Website here...

In the weeks before the Transit, Venus is sinking in the NW sky after sunset and is growing larger whilst showing a decreasing crescent phase - see the excellent image from the IAA's John Hall right.

IAA History

The eagle-eyed may have noticed a new tab on the drop-down menu - "IAA History". This is a work in progress - the Webmaster is pulling together, piece by piece, some items of history related to the past of the Association. Thus far we have records of Awards given by the Association together with past Presidents going back to the establishment of the Belfast centre of the Irish Astronomical Society in 1946.

In progress are the collection of all past officials and past speakers, as well as an improved archive of "Stardust", the quarterly magazine of the Association, so keep an eye on this new Tab - it will expand in months to come!

IAA AGM 18th April

Wednesday 18th April marked the date of the 38th Annual General Meeting of the Association. The purposes of the meeting were to review the activities of the past year, elect a new Council for the coming year and for the Council to receive feedback from the membership on how they - that's you - would like to see the Association develop.

The new Council was elected and is shown here...

Also, the Aidan P Fitzgerald Medal was awarded - this year to IAA Treasurer and Membership Secretary Jo Magill - a thoroughly well deserved award for the work Jo puts in, not just looking after the finances, but for the effort she puts in to almost every Outreach event, Meeting and Observing session!

"The Aidan P. Fitzgerald Memorial Medal is the prestigious award of the Irish Astronomical Association, and is named in memory of one of its leading members back in the 40's and 50's. It is presented not more than once per year for "Outstanding Service to the Association" to someone usually, but not necessarily in a Council post.

Aidan Fitzgerald was born in Limerick, Ireland and had a keen interest in astronomy since childhood. Later he bought telescopes and other equipment and set them up in an observatory in his back garden. He became a leading light in the Belfast Centre of the old Irish Astronomical Society, and later became Chairman. He was also on the editorial board of the Irish Astronomical Journal. By profession, he was a principal officer in the Northern Ireland Ministry of Health and Local Government, and had been awarded the O.B.E. He never married, and died suddenly in the summer of 1964 from a heart attack, just short of his retirement.In June 1954, the planet Mars was closer to earth than it had been for several years, but the most ideal conditions for observation were from the southern hemisphere. Astronomers from all over the world co-operated to make observations of the planet and a committee was set up under the chairmanship of Professor Earl C. Slipher from the Lowell Observatory in Arizona.

Slipher was probably the greatest authority on Mars and was to observe and photograph the red planet from the Lamont-Hussey Observatory at Bloemfontein, South Africa  using the great 27-inch refractor, (now dismantled)  Fitzgerald was invited to join him at the invitation of the National Geographic Society who sponsored the studies, which were to last some four months.

As to the medal itself, it is tastefully minted in bronze gilt, and on the obverse shows the profile of the famous "South Refractor" at Dunsink Observatory outside Dublin, while the reverse has the recipients name and date engraved inside a laurel wreath." (Many thanks to John C McConnell for the above words)

To provide some entertainment following the formal proceedings, long standing IAA member Michael Duffy talked to us about "Revenge of the Armchair Astronomer" which consisted of a look at the use of remotely controlled telescopes, notably itelescope.net which Michael uses for astrophotography.

Also included in the talk were some images from Michaels collection covering the rich history of the Association.

IAA Lecture 4th April


In a change to the advertised fixture, we were very pleased to welcome John Flannery who talked to us on "The Outer Limits: Exploring the Outer Solar System"

John lives in Dublin where he is Chairperson of South Dublin Astronomical Society. His interests in the hobby are the history of astronomy, outreach work, and delving into the science of naked-eye astronomy.

His professional background is in IT and he is currently studying for a BSc in Natural Science with the Open University. Although a Dublin resident for the last 25 years, John is originally from Dromineer, a small village by Lough Derg on the River Shannon in North Tipperary.

This was an illuminating look at the large part of our Solar System beyond the planets that we know and love.

Many thanks to John for stepping in at short notice!
