Closest approach will be at about 18.00, and the object should be visible in binoculars as it speeds past the Earth, with a maximum magnitude of between 7 and 7.5. Since it will be so close, and moving so fast, predictions need to be based on your own location, not geocentric. I'm very grateful to Dr Tolis Christou of Armagh Observatory who has generated an ephemeris for Belfast, giving the RA, Dec, Azimuth, Elevation and magnitude of 2012 DA14 from Belfast ( 54.6000° N, 5.9167° W) for the night of the 15th to the 16th of February 2013 every 5 min. The asteroid rises at 20:00 UT in Virgo, and will move rapidly Northwards through Coma, Canes Venatici, Ursa Major and Draco during its period of best visibility from here. It will remain brighter than mag 10 until 22:20 UT. At that time its altitude is 53 deg.
This ephemeris is too long and detailed to include here, but I will forward the details to anyone on request. It should be possible to record its motion with a time exposure on a digital camera with a reasonable zoom lens, and set to a high ISO setting.
This will be the brightest-ever NEO to be observed approaching the vicinity of our planet (<0.1 AU). It is predicted to be 30 times brighter and more than 150 times more massive than the next largest known object to approach as close or closer to our planet in recent years: that one was 2012 MD.
If you want to see what 'Armageddon' might look like before impact if one of this size was going to hit us, then have a look!
Planetarium Director Dr Tom Mason and Dr Mike Simms from the Ulster Museum will show you how to identify meteorites and also provide examples of the most commonly misidentified objects which are not meteorites. Feel free to bring along any rock samples that you would like identified.

One of the people badly affected is the well-known Scottish-Australian astronomer, Robert McNaught, who started his career as a BAA member, was awarded the Merlin Medal by the Association in 1987, and who has since gone on to achieve great things, discovering many more comets than any other person (his Daylight Comet of 2007 was especially spectacular), and finding several hundred near-Earth objects, mainly through his survey work at Siding Spring (part of the Catalina Sky Survey). Rob and his partner Tanya Smith
suffered the loss of their home and all of their possessions last weekend as a result of the fire that swept through the area. Rob's tale is featured on the Sky and Telescope website at: http://is.gd/f9A69D
Some funds have been set up to help the astronomers and their families. In particular there is the ANU Siding Spring Observatory Fire Staff Emergency Relief fund at:
And the "Robert McNaught and Tanya Smith Bushfire Recovery Fund" at: http://tinyurl.com/awcujrh.
(I feel a particular affinity with Rob, as I have an A1 size signed copy of his amazing photo of his own 'daylight comet' of 2007, showing that fantastic sweeping feathery tail.)
Astronomy: Our place in the Universe
Looking to the sky for the first time you may feel overwhelmed and confused by the spectacle of thousands of stars above your head. Astronomy is a great gateway science that can inspire you to do great things! Participants will gain enjoyment from exploring the wonders of the night sky. The topics covered include Greek mythology, Egyptian and Babylonian cosmology, Astrobiology, Quantum Physics, Terrestrial and Jovian planets and Solar System to help us understand our place in the cosmos. This is a great way for the community to come together and take a fresh look at our night sky.....it belongs to us all. No experience necessary and questions encouraged!

The Greenwood Players and the Armagh Observatory are presenting in the Armagh Observatory from 22nd to 24th February 2013 the first performance on the island of Ireland of the play "The Life of Galileo" by Bertolt Brecht in a new version by David Hare.
The story of the Life of Galileo and its central drama of the conflict between science, religion and authority is one that resonates today. As remarked by Ian McDonald, author and Executive Producer with the Greenwood Players, "The Life of Galileo" is a story that needs retelling every generation, especially in a 21st century when we seem to be moving away from science to an authority and belief-based worldview.
There will be five performances of the play: two matinees at 2.00pm on Saturday 23rd and Sunday 24th February, and three evening performances at 7.00pm on each of 22nd, 23rd and 24th February. Tickets, which are strictly limited, cost 12 pounds and are available from 14th January 2013 at http://galileoattheobservatory.eventbrite.co.uk/.
