1. TV Thursday 5:55pm RTE 2 Astronomy Ireland Chairman, David Moore (www.astronomy.ie/dmbio.html) will be on RTE 2 television this Thursday June 1 around 5:55pm to explain why anyone in Ireland thinking of going to university really must be thinking of taking a degree in astronomy or nothing at all! Yes, it really is that simple and about 100 billion euro a year is at stake to Ireland's economy! It's a crisis that is looming and astronomy CAN save the Celtic Tiger. Tune in or set your video for more. Thinking of studying astronomy? For details of AI's October Evening Classes and EVERY astronomy degree course for full time students in Ireland see www.astronomy.ie and click "Study Astronomy" in the left-hand side menu. 2. RECORD YOUNG MOON and VIEWING THIS WEEK In the May issue of our magazine, Sky Diary author David Grennan (www.astronomy.ie/DG1bio.html) challenged you to spot the youngest Moon ever seen from Ireland. Declan Meyler from New Ross, Co. Wexford smashed David Moore's 21.7 hour record set in 2003 by viewing the Moon last Saturday just 15.6 hours after New Moon, using a telescope from our Shop! Declan writes: On the evening of Saturday the 27 of May I decided to try locate a very young Moon. I had read in the A&S SkyDiary that a 15.5 hour old Moon could be visible in large binoculars or telescopes. The north-western sky was very clear so shortly before 10pm I first located the planet Mercury, which was only 4 degrees to the left of the Moon, using my Celestron NexStar 11 and a 22mm Nagler eyepiece. The planet was easily visible through the eyepiece and also visible through the finderscope. I then selected the Moon on the hand control unit of my telescope and pressed enter. The telescope moved slightly to the right of Mercury and as I looked through the eyepiece I could only see the yellow-orange colour of twilight. Then after about 30 seconds I spotted an extremely thin sliver of light which took on the same colour as the twilight itself, the time was exactly 10pm(2100UT). I could trace an arc of about 20% of the Moon's circumference of which small sections would appear to brighten and fade, this was due to the atmosphere and low altitude. By 10:10pm the Moon was slightly easier to see and I followed it for another 10 minutes before it disappeared behind some distant low cloud. Few people in the world have seen the planet Mercury and fewer again such a young Moon, so it was nice to see them close together in the sky. See pages 27-28 of the May issue of our magazine (still available by post at www.astronomy.ie/sub) for more details and diagram. Congratulations to Declan on setting a new Irish record. The world record is 11h 40m by the way and we'll keep you posted of future opportunities to see very thin crescent Moons in the SkyDiary of our magazine. THIS WEEK's viewing highlights include: MARS - low in West each evening near Castor & Pollux and closing in on Saturn. Sets 1am. Disk very small in a telescope now. SATURN - low in West each evening but passing very close to Beehive star cluster this week - an amazing and rare sight! Moon nearby Wednesday. See magazine!!! JUPITER - brightest 'star' in the sky in the south all evening. Times to see Great Red Spot every evening are in magazine. New red spot one hour behind GRS! Details in July magazine, out soon. MOON - crescent early in week, First Quarter on Saturday. Visible in evening sky all week. Superb sight in a telescope this week therefore. Very near Regulus Friday! Some BRILLIANT viewing events this week therefore! Check out our magazine Sky Diary pages for details and diagrams and tune in to our Radio Show on Tuesday nights. Always send your sightings, like Declan did, to observe(a)astronomy.ie and be recorded for posterity in our magazine. 3. Lecture June 12 "ADAPTIVE OPTICS" Prof. Chris Dainty will give a PUBLIC LECTURE for Astronomy Ireland on Monday June 12 about the fascinating developments in sharpening the images produced by large ground based telescopes.

[Astronomy Ireland] naked eye comet, SALE NOW ON, Briefs
by Astronomy Ireland 16 May '06

16 May '06

1. Comet Schwassman-Wachmann 3 ("SW3" for short!) has been seen by many of you with the naked eye from Ireland. A report will be in the Observers Log pages of the magazine so please send in any more sightings to observe(a)astronomy.ie The May issue of our magazine has a 2 page report, and diagrams of how to find this comet on pages 28 to 29. The comet reached about magnitude 5 as is whizzed past Earth last Friday just 7 million miles (11 million km) away - very close as comets go. It will be closest to the Sun on June 6 so it will not fade much in the next few days and it could undergo another of the several outbursts it has already had as its splits in to 100 pieces or so (though the 2 brightest fragments labelled "C" and "B" are all most of us are likely to see in binoculars or with the naked eye). This week the comet moves from Pegasus into Pisces as the diagram in the magazine for the shows (order A&S May issue at www.astronomy.ie/sub for 5euro including P&P and support Astronomy Ireland) 2.
