Ignore the usual media hype - this passage will not be "Spooktacular" whatever that means. It won't even be 'spectacular', as it will never get brighter than 10th magnitude! Details as follows.
A just-discovered asteroid about 300 meters across (H=19.8), named 2015 TB145, will come 'very' close to the Earth this W/E. Only one object of that size is known to have ever come closer to the Earth. Although 300 near-Earth asteroids have passed closer to the Earth than this one, but of these 'TB145' is the SECOND largest to do so after 2004 XP14 which came by in 2006 at 1.16 LD. And it will be 2027 August 7 until the next known object (1999 AN10) that is larger than this one to come closer to the Earth.
The closest approach will be 1.26 lunar distances (485,000 km). To put that in perspective, that's 38 Earth-diameters away. So it's not really even a 'close shave', but on the other hand if one that size did hit us, the effects would be catastrophic!
It will likely brighten to about magnitude 10 or brighter on afternoon of October 31, then at declination +45. Magnitudes in the hours before closest approach:
29/10/2015 18 UT: 14.3

VENUE: Bell Lecture Theatre, Physics building, QUB. Free parking on Campus after 5.30 p.m. Admission free, including light refreshments.
At key points in human history, civilization took a leap forward because people discovered a new way of harnessing nature. Tool making, farming, the industrial revolution, and the information age were all triggered by the discovery of new ways of manipulating nature. By harnessing the Alice in Wonderland like effects of quantum physics, Quantum computers could help realize true artificial intelligence, offer insights into nanotechnology, teleportation and time travel, change the way chemists and biologists study the molecules of life and design drugs, and break supposedly unbreakable secret codes… tasks well beyond the capabilities of any classical supercomputers.
The D-Wave Systems Inc team, based in Vancouver, has created the first, special purpose quantum processors in a scalable architecture. D-Wave's exciting, first generation quantum processors, now being explored by Google and NASA, as well as Lockheed and the University of Southern California, may, in just a few short years, exceed the capabilities of existing classical computers.
In this lecture, Eric Ladizinsky, Co-Founder and Chief Scientist at D-Wave Systems Inc will outline the basic ideas behind quantum computation, summarise D- Wave's unique approach, and provide answers to some frequently asked questions about quantum mechanics, quantum computing, and D-Wave quantum computers.
Prior to his involvement with D-Wave, Eric Ladizinsky was a senior member of the technical staff at TRW Inc's Superconducting Electronics Organization, where he contributed to building the world's most advanced Superconducting Integrated Circuit capability, intended to enable superconducting supercomputers to extend Moore's Law beyond CMOS. He has a BSc degree in Physics and Mathematics from the University of California, Los Angeles and is an Adjunct Professor of Physics at Loyola Marymount University. http://www.dwavesys.com/
Refreshments will be available from 5.30pm, before the lecture.

Just letting you know that on Friday 25th September I launched a crowd-funding KICK-STARTER campaign to get Ireland's TWO Astronomy themed books published. Research shows that these may well be the first Irish Astronomy books (or at least Irish Authored) ... so am very excited about that.
The total needed to be raised is e6,700 in 40 days. NO MONEY is taken from anyone's account until ALL the money is raised, this protects the sponsorer. If the target cost isn't raised in the allotted time then these 2 books wont be published in the foreseeable future. PLEASE can you help by mentioning the campaign on all your media....computer, blog, email etc Acknowledgement of your help will be mentioned in the books.....Thank you so much. Julie 087 7845688
Astronomy clubs and non-profit organisations from 45 countries submitted 247 proposals for the names and so far the contest received more than 300 000 votes, becoming one of the largest outreach astronomy projects in the world. We, at the IAU Office for Astronomy Outreach, would like to thank everyone that supported NameExoWorlds and to all participating institutions that sent special videos stating why their name proposals should win.
If you haven't voted yet, we urge you not to miss this chance.
And if you need any support from our team just let us know via email@example.com.
Best regards,The IAU Office for Astronomy Outreach team
Celebrate 51 Pegasi b's 20th anniversary by voting for its new name
October 2015 marks the 20th anniversary of the announcement of the discovery of 51 Pegasi b; the first exoplanet to be discovered orbiting a Sun-like star. This is an exciting opportunity to celebrate the many discoveries that have been made since then. 51 Pegasi b is also one of the planets awaiting a new name as part of the IAU's NameExoWorlds contest. NameExoWorlds has been running since August, and the number of votes for the submitted name proposals have gathered more than 300 000 entries from all around the world. If you still haven't voted, don't miss this great opportunity, and vote before the closing date of 31 October.
You can find the details of the contest here: http://nameexoworlds.iau.org/.
