Subject: Lecture 2nit, Binocs, Donation, Ireland to Mars? V young Moon + 22 other items!


Hi all,

 

1: IAA LECTURE TONIGHT: Next IAA public lecture:  Feb 18, 7.30 p.m. by Dr Jorick Vink, Armagh Observatory: "Star Formation in the Milky Way and in the early Universe". 

We are delighted to have Jorick back again to give another of his excellent lectures. Jorick is a Senior Research Astronomer at Armagh, specialising in very massive stars and star formation. This is a fascinating subject, as we are constantly discovering older and older stars, including one which had a nominal age older than that of the universe itself. But within the error bars of the estimate, it just fell within the estimated age of the universe, which is 13.8 billion years.

    The lecture is free and open to all, including free refreshments. Venue: Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.  

   Thanks to the Astrophysics Research Centre, QUB, for help in hosting these lectures.

    

2. Lidl binocs bargain: Lidl (N.I.) will be selling Bresser Compact 12x32 binocs for only £9.99 a pair from Thursday 19th. These are not ideal for astronomy, as they are only 32mm aperture, and the field of view is not large, but they are compact & a lot better than the naked eye alone! I haven't had a chance to check the quality yet, but from past experience with Bresser they are probably OK, if not really good. At that price they would do for projecting an image of the Sun during the upcoming eclipse - more on that in next bulletin.

3. Thanks to Sam Lyttle for donation: Sincere thanks from me and all in the IAA to Sam Lyttle for a very generous donation of telescopes and equipment to the IAA! We will do our vest to ensure that they are put to good use.

 

 

4. Mars One Final 100: One from Ireland

Congrats to Dr Stephen Roche from TCD who has made it through to the final 100 for this challenging mission. See https://community.mars-one.com/profile/f735a7a7-27c3-471c-b87d-c04b3799e026 Good Luck to him (although as I've already stated, I have my doubts about whether they're ready to go as soon as they plan!). See http://www.dailymail.co.uk/sciencetech/article-2957309/Meet-33-Americans-live-MARS-never-return-Mission-reveals-final-longlist-manned-one-way-journey-red-planet.html One is 60 NOW? There had better be Pensions benefits on Mars, because that's the age he'll be when he gets there!

For other background info, see for example http://www.wired.com/2012/07/medicine-psychology-space/#slide-586763 

  

5. See a VERY young Moon, Feb 19. On the evening of the 19th you can look for the wafer-thin crescent of a very young Moon. New Moon occurs on Feb 18 at 23.47. If you see the Moon next evening at around 18.00 it will be just over 18h old! You will need exceptionally clear sky right down to the SW - W horizon, and you'll only have a 'window' of about 10 minutes to see it before it gets too low and sets. It will appear just as a thin curved thread of light, and you'll probably not see the whole 180 degrees of the curve. Use binoculars to look for it (but ONLY after sunset!), but it only counts as a sighting if you can see it with the naked eye!

   

6. Jupiter. Jupiter was at opposition on Feb 6, appearing at its biggest and brightest for the year mag -2.6, diam = 45.3" (arcsecs)

MUTUAL JOVIAN SATELLITE EVENTS: 

20 Feb: 00h 34m 55s - 00h 43m 25s: Io eclipses Ganymede, mag drop 0m.84

22 Feb: 02h 04m 37s - 02h 11m 02s: Europa occults Io, mag drop 0m.57

22 Feb: 02h 41m 28s - 02h 48m 51s: Europa eclipses Io, mag drop 0m.90

24 Feb: 01h 42m 00s - 01h 47m 30s: Ganymede occults Io, mag drop 0m.57

 

7. Venus conjunction with Mars:  Venus is now very prominent in the SW evening twilight, and getting higher in the sky at any given level of twilight.

  Watch it close in on much fainter Mars over the next few days, leading to a very close conjunction on Feb 21 & 22, and they will also be joined by a lovely thin crescent Moon on the 20th and 21st - a great photo opportunity.

  On Feb 19 Venus will lie only 1.2 degrees below and right of ruddy Mars: watch that separation shrink to less than half a degree on the 21st & 22nd.

Close conjunction: Also, on the evening of the 21st Venus (mag -4.0) will lie just 2' S of star TYC 4663, mag 6.3. That's just about 1/15 of the diameter of the Moon! That difference of 10.3 magnitudes corresponds to a difference in brightness of over 10,000. Yet of course Venus has no light of its own, shining only by reflected sunlight; whereas the star is 50 times brighter than our Sun! The star appears fainter simply because it's 470 Light Years away, whereas Venus is only 212 million km away, or about 12 Light Minutes.

 

8. Light Pollution talks: Prof Brian Espey of TCD will be giving a talk on the problem of LP to the IAS on Monday 23rd Feb in Ely Place, Dublin.

17. Armagh Observatory St Patrick’s Day Event “Discovering the Sun and Stars at Armagh"

See: http://star.arm.ac.uk/press/2015/stpatricksday2015.html

 

 

18. LARGE PARTIAL SOLAR ECLIPSE, 20 MARCH: The IAA is finalising plans for SAFE public viewing of this really major event, at various locations around N.I. It will occur in the morning, with maximum eclipse around 9.30 a.m. These will include the North Coast, QUB in Belfast, North Down, and others. More details in next bulletin. Details of the eclipse itself were given in the last issue of our magazine STARDUST; I'll be updating and expanding these in the next bulletin.

Request: Eclipse viewing in L'Derry (From Prof Mark Bailey, Armagh Observatory)

We are doing an outreach event at St Cecilia's College, Londonderry, timed to coincide with the partial eclipse of the Sun on Fri 20th morning; and then a performance of "aroundNorth" that evening in a nearby housing estate in the same part of Derry, from around 7pm to 9pm. I was wondering whether any IAA members might be able/willing to travel to the site (particularly in the evening) to provide telescope-viewing

opportunities that evening (if clear) to complement the aroundNorth event. We could provide some financial assistance through the provision of a small mileage payment at the usual rate of 45p per mile.

   If there are any IAA members in that area who would be prepared to help out with this event, please contact Prof Bailey directly at mebat signarm.ac.uk 

 

19. Safe Solar viewing material available: Baader safe viewing foil now in stock ... just in time for the big eclipse! £19 for an A4 sheet delivered. Contact Dr Andy McCrea at s.mccrea980at signbtinternet.com

22. ARCHAEOASTRONOMY TRIP TO NEWGRANGE and KNOWTH, 9 May 2015, These trips have proved so popular that as soon as I got back from the last one, Stranmillis University College Institute of LifeLong Learning asked me to lead another one next spring!  Like the last one, the next trip will include a visit to the Knowth Tomb as well. It has the largest collection of Megalithic art anywhere in Europe in one single site, some of which is reckoned to be astronomical. Booking for thus very popular, non-technical trip will open later, but if you want to go, note the date in your diary: Sat 9 May. More details when the new brochure comes out.
