Observing night Sat. 3rd. March for Lunar eclipse

Hi Folks,

On Sat. evening 3rd. March we will enjoy a total lunar eclipse (weather permitting) and so we are arranging an observation night at Cultra. Details as per Terrys following note.

 

AA ECLIPSE OBSERVING EVENING: The IAA will be having a special eclipse observing event at the Lower Car Park (on the seaward side of the main road), Ulster Folk & Transport Museum, Cultra, Co Down, starting at about 8 p.m. that evening. We'll have a selection of telescopes & binocs to observe Saturn and other night-sky delights, as well as the eclipse, so wrap up warm and bring a flask & some food to sustain you to almost midnight! Bring your own portable telescope & binoculars too, if you have them. Bring your digital camera too - you might get some great shots.

 

Obviously it depends on the weather: check the IAA website for updates nearer the time: www.irishastro.org

 

**As per normal, check the forum for any change of detail around 6.30pm on Sat.

Hope to see you there.

WEATHER SITE

Thanks to Colin Campbell for the following tip: "Here’s something that might be of interest to those with little faith in the weather forecasters…
Mentioned in the Letters section of February’s Sky at Night magazine, http://www.metoffice.gov.uk/satpics/latest_uk_ir.html provides access to hourly, infrared satellite imagery of the UK and Ireland. Pressing the Play button downloads all the images and animates them, aiding prediction of cloud cover, before going to the bother of setting up for an observing session. Images in the visible spectrum are also available, but possibly less useful. Images are uploaded to the site approx 20 mins past the hour. The ‘Global satellite imagery’ is worth a look too, just for interest. [Obviously you'd need to delete old images fairly regularly or you'' soon clog up your hard drive! T.M.]

SEMINAR at DCU, on 1 March

The following seminar will be held at the School of Physical Sciences, DCU.

"Probing the first galaxies and clusters in the early Universe using Radio Sources", by
George Miley, Leiden University, NL.
Sponsored by Institute of Physics in Ireland. See: http://www.dcu.ie/physics/seminars/index.shtml

Total Lunar Eclipse on 3 March: A Ruddy Moon for Ireland!

A Total Eclipse of the Moon occurs when the Moon passes into the shadow of the Earth. It can only happen at Full Moon, but it doesn't happen every Full Moon because the Moon's orbit is tilted to ours by about 5 degrees, and so usually it passes above or below Earth's shadow, rather than through it. And sometimes it only passes through the edge of the shadow, giving a partial eclipse. The next total one visible from Ireland will be on Feb 21, 2008.

But this is a good one for Ireland, with all stages of the eclipse visible, and the main part occurs before midnight! If it's clear we'll see the Moon turn a glorious reddish colour - anything from a sort of ochre, to deep red. The exact colour can't be predicted, which is one of the fascinating things about such eclipses. The colour is due to the Sun's light passing through the Earth's atmosphere, which acts like a giant lens, focussing the light onto the Moon so that it never goes totally dark.


The Moon starts to enter the Penumbra, Earth’s faint partial outer shadow at 20.18, and then begins to enter the darker main shadow or umbra at 21.30. It will be completely inside the umbra, i.e. the eclipse will be total, from 22.44 to 23.58, with Mid Eclipse at 23h 21m.

It will have left the umbra at 01.00, and will finally exit the penumbra at 02.24, marking the end of the eclipse.

The penumbral stages are barely noticeable, and it will probably be a few minutes after the start of the umbral phase before you'll notice the lower left side of the Moon start to darken slightly: say about 21.35.

This darkness will gradually spread across the Moon until by about 22.45 it will all be immersed in the shadow of the Earth. However, it won't all appear equally dark, as the Moon does not pass through the centre of the shadow, and even at mid-eclipse at 23h 21m you'll notice that the top left of the Moon won't be as dark as the bottom right, which will be closest to the centre of the shadow.

The Moon will be quite high up in Southern Leo, near Chi Leonis, with Saturn about 24 deg away to the upper right.

The Moon will occult 5th magnitude 59 Leonis after the total phase ends, at about 00.43 for observers in Belfast, and about 00.30 for observers in Cork. That event would be visible in a small telescope.

IAA ECLIPSE OBSERVING EVENING

The IAA will be having a special eclipse observing event at the Lower Car Park (on the seaward side of the main road), Ulster Folk & Transport Museum, Cultra, Co Down, starting at about 8 p.m. that evening. We'll have a selection of telescopes & binocs to observe Saturn and other night-sky delights, as well as the eclipse, so wrap up warm and bring a flask & some food to sustain you to almost midnight! Bring your own portable telescope & binoculars too, if you have them. Bring your digital camera too - you might get some great shots.

Obviously it depends on the weather: check the IAA website for updates nearer the time: www.irishastro.org

Other societies will probably be organising their own events too - contact your local club for details.

ASTRONOMY SUMMER SCHOOL

Enterprise Ireland offers support (approx €1,500) to a number of successful Irish candidates to attend the Alpbach summer school. I would be grateful if you would circulate this to science and engineering researchers. An outline is given below and further details are on the summer school website.

Space Education Summer School, Alpbach, Austria, 17-26 July 2007

“Astrobiology:- Life Detection in and from Space

As in previous years the Austrian Space Agency, now incorporated into the Austrian Research Promotion Agency (FFG), is running a ten-day Summer School on a leading-edge Space Science topic from 17th to 26th July 2007. The event will be held at Alpbach (Tyrol, Austria), and this year’s topic is “Astrobiology:- Life Detection in and from Space”.

The objection of the Alpbach Summer School is to provide young science and engineering graduates, whether postgraduate students or already in the workplace, with an opportunity to advance their education in the field of space science and space technology.

Candidates should apply directly to the Austrian Research Promotion Agency (FFG) in order to be considered for the course, and applications need to reach FFG before March 31st 2007. Applicants should already hold a primary degree or equivalent in science or engineering.


This Austrian Summer School endeavours to limit the number of participants to 60, from across the full range of European countries. Details can be found on the website: http://www.summerschoolalpbach.at. Enterprise Ireland funding (approx 1,500 euro) – to cover course fees, travel, accommodation etc – will be available for a number of successful Irish candidates. Once notified by FFG, such candidates should make contact with Enterprise Ireland to discuss financial support.

ASGI meeting, 3-4 April

The Spring meeting of the Astronomical science Group of Ireland will be held at QUB on Tuesday & Wednesday, 3-4 April. The meeting will begin late morning on the 3rd to allow time to travel to Belfast.
A meeting website with suggestions for accommodation and travel directions is under construction and will be linked soon off the ASGI meetings page:
http://www.arm.ac.uk/asgi/Meetings.html

Please note that these meetings are at a professional level, and so most of the talks are not suited for the average amateur! Members of affiliated Societies such as the IAA are entitled to attend, but please let the organiser, Mihalis Mathioudakis (M.Mathioudakis@qub.ac.uk), know if you plan to attend so that he can gauge numbers.
