Hi all,
Òš
1.ÒšÒšIRISH ASTRONOMICAL ASSOCIATION Public Lecture, March 5, 7.30pm:ÒšÒšÒš"Making Your Own Telescope", by Dave Grennan. NB: this replaces the previously advertised lecture byÒšCarl O'Beirnes, who has had to cancel at short notice for personal reasons. We are VERY thankful to Dave for stepping in at short notice.
ÒšÒš DaveÒšis also one of Ireland's best-known amateur astronomers, and he alsoÒšhas built a very advanced observatory, with which he was one of the very first to discover a newÒšasteroid from Ireland. He's also a redoubtable telescope maker, with an amazing project under way at the moment, and he will tells us about that, as well as the simpler principles involved for anyone who wants to have a go at it.ò??
Òš The lectureÒšis free and open to all, including free refreshments.ÒšVenue: the Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.Òš
ÒšÒš Thanks to the Astrophysics Research Centre, QUB, for help in hosting these lectures.
(This lecture forms part of the IAA's participation in National Astronomy Week)

2.ÒšGood aurora seen: A CME hit Earth's magnetic fieldÒšon Feb. 27th @ 1645 UT), and the impact triggered geomagnetic storms around Earth's poles.Òš The CME was an after-effect of the X4.9 class solar flare reported on Feb. 25th.Òš Observation of aurorae were reported widely from UK & North Ireland - see IAA website for some nice photos: www.irishastro.org. Also http://www.huffingtonpost.co.uk/2014/02/27/northern-lights-aurora-borealis-britain_n_4869848.html

3. Bright Asteroid Occultation, 7 March:Òš(From theÒšBAA)
On 2014 March 7 at 0308UT, (Night of March 6/7)Òšthe main belt asteroid (9) Metis (diameter 200km) occults a v7.9 star in Libra, HIP 78193. ÒšThis favourable event (99%) is visible over much of the UK & Ireland and presents an ideal opportunity toÒšrecord an asteroid occultation visually. Òš Observe from 0306 to 0310 UT
Finder charts can be found on asteroidoccultation.com
http://www.asteroidoccultation.com/2014_03/0307_9_32274.htm
Òš The maximum duration at the center of the shadow is predicted to be 24.5sec. and the magnitude drop is 3.3 magnitudes.ÒšTo a visual observer the starÒšwill disappear, although the asteroid should remain visible with larger apertures, Video or CCD at magnitude 11.Òš Observers situated near the edge of the occultation path will experience shorterÒšdurations.ÒšA Miss event should be reported if no occultation was detected.
ÒšÒš Timings of the duration and UT of disappearance are desired over as wide an area as possible. Conditions allowing, this could be the first observation of a Metis event for UK observers. There have been 11 observed occultations since the first reported in 1979. ÒšAn event seen in California in 2008 was perhaps the best observed to date with 26 observations, with three observers operating an unattended video station.Òš
ÒšPlease send timed observations (Aim for an accuracy of 0.5 sec or better) toÒšarpsbritastro.org, including your name, instrument, timing method, and your Google Earth co-ordinates. (Datum WGS84).
Òš Good luck and best wishes. Tim Haymes, BAA Asteroid and Remote Planets SectionÒš- Occultation Co-ordinator

NB: Metis was the first, and until recently the ONLY asteroid discovered from Ireland! (by Graham, at Markree ObsÒšin Sligo, in 1949). The latest prediction shows the S limit of the track running roughly from Galway to Rosslare; all of the rest of the island of Ireland is within the track. The 1 sigma error limit at the S limit of the track would bring it roughly from the Burren to Waterford.
ÒšÒš Observations at the S limit would be particularly valuable, as they set a constraint to the diameter of the asteroid in that direction. If you observe and DON'T see an occultation, that is just as valuable, so report your details & exact location.
ÒšÒš Text in the linkÒšsays it may be double, but Hipparcos lists it as single. However, any stepped variation in brightness (extinction or reappearance) should be carefully noted. The star is solar typeÒš(F5), a little bit bigger than the Sun, and at a distance of ~245 LY, so there would be no 'disc' effect - extinction of one, or both, components should be instantaneous.

4. IAA / St Patrick's Academy, Dungannon: Friday 7 March.
ÒšThe IAA will be returning to this venue with yet another of their very popular astronomy evenings, with observing using the school's own 14" Celestron in its big dome, and some of our own telescopes, if clear. Also presentations on astronomy & observing, telescope workshop, exhibitions, etc. Start 7.30 p.m. See IAA website for more details: www.irishastro.org.Òš

5. ESA selects planet-hunting PLATO mission
ÒšÒšò??A space-based observatory to search for planets orbiting alien stars has been selected today as ESAò??s third medium-class science mission. It is planned for launch by 2024.ÒšThe PLATO (Planetary Transits and Oscillations of stars) mission was selected by ESAò??s Science Programme Committee for implementation as part of its Cosmic Vision 2015ò??25 Programme. The mission will address two key themes of Cosmic Vision: what are the conditions for planet formation and the emergence of life, and how does the Solar System work?ò??.

6. Dark Skies Competition: Second ò??Dark Skies Rangers" contest (deadline 20 March 2014)
ÒšÒš The second consecutive Dark Skies Rangers contest kicks off to inspire and make awareness of the importance of the dark skies. Our planet, seen from the International Space Station, looks like a Christmas tree. This light, visible from space, is called ò??light pollutionò?? caused by street illumination that project the light to all directions, diminishing greatly the darkness of the night sky. Light Pollution is a global problem that we have to fight for. It contributes to a major waste of both energy and money, influence the climate change, affects living beings, prevents people from enjoying the beauty of the sky and disturb astronomical observations.
ÒšÒš In order to promote the project Dark Skies Rangers, the Dark Sky Alqueva Reserve, a night sky tourism destination certified by the Starlight Initiative, and NUCLIO ò?? NÓÊcleo Interactivo de Astronomia (Galileo Teacher Training Program) are organising the Dark Skies Rangers Contest for students and teachers with the objectives to stimulate the interest for research related to light pollution, promote the production of projects related to light pollution, develop skills in the field of: eLearning, writing, photography, video and artistic expression, contribute to establish a community of informed citizens, that participate in the solution to issues like this and with critical thinking about science in our daily lives.
ÒšÒš The contest is open to teachers and students between 6 to 18 from any country. Deadline is 20 March 2014. More info at: http://dsr.nuclio.pt/contest/. Winners will get a week in the Alqueva Dark Sky Reserve (Portugal), a tablet and a smartphone: http://www.galileoteachers.org/save-our-sky-and-win/

http://www.dailymail.co.uk/sciencetech/article-2565418/Stargazers-best-view-Jupiter-years-largest-planet-solar-moves-prime-position.htmlÒšThere are two errors in the information 'box' How best to see Jupiter.
1. They omitted the rest of the information after "From March 1" It won't be at its best 'until 2026'! It should say for about a week from March 1....
2. And Jupiter will set in the WEST not the East

http://www.space.com/24784-big-bang-theory-five-weird-facts.html?cmpid=556717Òš The last 'fact' in the linkÒšis not true. Cosmic expansion only applies on the very large scale.ÒšIt does not apply within galaxy clusters, such as our 'Local Cluster' containing, inter alia, the Milky Way, M31 and M33, where the gravitational attraction between the galaxies is stronger than the cosmical repulsion force whatever it may be. Indeed, it's probable that the expansion does not apply even at the scale of superclusters, such as the one containing our Local Cluster and the Virgo cluster.
ÒšÒš However, there is the possibility that all the clusters in a 'Local Cluster' will eventually merge, and even that it might also happen to all those on a Supercluster.

http://www.space.com/24811-mars-crater-name-project-uwingu.html?cmpid=556717ÒšThis is not much better than the unofficialÒš'name a star' schemes which have no validity whatsoever, and exist only to make money for their operators. If it's true that the money raised on this one will go "to fund grants in space exploration, research and education, which is the company's stated chief purpose" then that's better than nothing, but I still wouldn't recommend it.

Or does it mean 'massive', but at the low end of the 'massive' category? Or do they just mean 'particles with mass'?ÒšA bit confusing to me....
http://www.sciencedaily.com/releases/2014/02/140226075019.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Ftop_news%2Ftop_science+%28ScienceDaily%3A+Top+Science+News%29ÒšCurrent turbines may be able to "withstand" winds of up to 112mph, but only in safe mode, i.e. not operating, with the blades either feathered, or turned sideways to the wind. So they would present minimal resistance to the hurricane winds, and thus slow them down only very slightly.
ÒšÒš Any turbines which were turning in such winds would soon tear themselves to pieces! And if the hurricane was category 4 or 5 (like Katrina) you wouldn't have many turbines left, even if they were in safe mode! I'm sure no energy company in their right mind would build that many turbines in a hurricane area. TM
