From: TerryMoselaol.com Date: Sun, 11 Sep 2005 17:57:37 EDT Subject: Aurorae, ISS, Broadcasts, IAA at Argory, Major Lecture Hi all, 1. AURORA ALERT: Our amazing Sun continues to, well, amaze! Although supposedly approaching the minimum of its 11 year cycle, there's a huge and very active sunspot, now on its second rotation, firing off major flares, capable of causing aurorae tonight & over the next few evenings. Sunspot 798 / 808 has unleashed seven X-class solar flares since Sept. 7th. Forecasters say there's a 75% chance of more X-flares during the next 24 hours, possibly causing radio blackouts and radiation storms. Coronal mass ejections hurled into space by these explosions could hit Earth's magnetic field in the days ahead. Sky watchers should remain alert for auroras. The best time to look is around local midnight. The sun's 27-day rotation is slowly turning sunspot 798 / 808 to face Earth. Explosions in the coming week will be increasingly Earth-directed, raising the possibility of geomagnetic storms and auroras over northern latitudes, including Ireland. If you get any photos, send them in to iaa2000btinternet.com for the IAA website. 2. ISS: The International Space Staion continues its series of evening passes over Ireland until 17 Sep. Check www.heavens-above.com for all the details of these passes for your own location, plus of course Iridium Flares, other satellites, sky viewing details etc. 3. Radio & TV. Some interesting programmes are promised for the week ahead. Mon, 12 Sep, 7.00pm, BBC4 TV: Reach for the Stars - Yuri Gargarin, first man in space. 9.00pm, BBC4 TV: The Wild Blue Yonder - an uninhabitable Earth? 10.20pm, BBC4 TV: Space Odyssey: The Robot Pioneers - history of space exploration. Tue, 13 Sep, 3.00pm, 7.00pm, RTE2 TV: Naked Science - newly discovered planets. Wed. 14 Sep, 7.00pm, BBC4 TV: Neil Armstrong's first step on the Moon. 9.00pm - 10.00 p.m., BBC2 TV: Space Race - First of a 4-part docudrama series on the race to put a man on the Moon. Thu, 15 Sep, 9.00pm, BBC2 TV: 'Horizon' on Stephen Hawking's latest theory, in which he retracts from his last controversial proposal, and attempts to develop his latest one. Fri, 16 Sep, 7.45pm, BBC R4: Short play about the first steps on the Moon. 4. IAA at The Argory. On Sat 17 September from 13.00 - 16.00 the IAA is putting on another special telescope / solar afternoon as part of a charity event at the National Trust property "The Argory", near Moy, on the Armagh/Tyrone border, roughly in the middle of the Armagh - Portadown - Dungannon triangle. It's well signposted from the M1, and other roads in the region. If you have a telescope, particularly one with solar filters and/or a solar-projection set-up, come along and help. If it's cloudy we'll have a static display and show some Videos / DVDs. Admission free for IAA members with telescopes, & you'll probably get some free grub & drinks too. 5. MAJOR LECTURE: The first lecture in the IAA's new season kicks off, appropriately enough, on Wed 21 Sep, in Stranmillis College as usual. We are delighted to have world-famous astronomer and world-leading astro-biologist Prof Chandra Wickramasinghe, Professor of Applied Mathematics & Astronomy at Cardiff University of Wales, Director of the Cardiff Centre for Astrobiology, FRAS, FRSA. The title is "Where are we in our search for Origins?" and will look at the evidence that life on Earth (and presumably on other planets), came from space; most likely from giant comets. His astro-biology theories, developed in association with the late Prof Fred Hoyle, have always been controversial, but seem to have got a boost from some of the findings from the Deep Impact mission, which indicate that there may be a lot of organic material inside some comets. Not to mention the ever increasing number of large & interesting bodies being discovered in the Outer Solar System! Come along and hear for yourself - this promises to be a highly interesting and challenging lecture! It starts at 7.30 p.m., Lecture Room 5, main building, Stranmillis College, Stranmillis Road, Belfast. Come early to get a good seat. Light refreshments will be served as usual. Clear Skies, Terry Moseley
