From: TerryMoselaol.com Date: Sun, 28 Aug 2005 22:06:05 EDT Subject: Armagh Observatory Event, ISS, Google Earth Hi all, 1. Just a reminder about the event for Pat Corvan, who recently retired after many years at Armagh Planetarium, who was honoured with the naming of asteroid '8515 Corvan' earlier this year. On Tuesday August 30th there will be a special event, organised by the EAAS, at Armagh Observatory starting at 7pm. This will be an opportune time for friends of Pat who have never been to the observatory to come along. There will also be a special formal presentation to Pat to celebrate the naming of asteroid 8515 Corvan. A finger buffet will follow the formal proceedings. Following the buffet there will be tours of the observatory by the Director Professor Mark Bailey and members of his staff. If we are lucky with the weather, we may even get to observe with the famous 10" Grubb refractor just recently refurbished. If you plan to attend please contact Mrs Aileen McKee at the Observatory on 028 3752 2928 or ambnarm.ac.uk so that they will know how many to expect. 2. The ISS starts another series of evening passes over Ireland on 31 August: details as always on the excellent www.heavens-above.com 3. GOOGLE EARTH. If you haven't seen it, be prepared to be amazed! Look at 'Google Earth'. You need a fast processor & a broadband connection to get the best out of it, but if you do, it will blow your mind! It's a complete image of the whole Earth using all the best satellite images. You download a file (about 11 Megs?) first, them stream via the Internet. You can go to any location by typing in the name of major cities etc, or by latitude & longitude, or by just scrolling around, rotating, etc. You can then zoom in to an incredible magnification! Some areas have more highly detailed images than others. I zoomed in on the 'Ground Zero' site in New York, and saw individual trucks & cars, and what I'm sure was a person with his/her shadow! I looked at Hawaii, and the medium magnification view not only showed the islands, but all the submarine land features too! Ireland isn't all imaged at the same scale - Belfast/N.I. is not as hightly detailed as some other areas such as Dublin & Cork, where you can see individual streets, with cars & trucks on them! Best of all, it's in 3-d! You can vary the angle of view, and zoom down the Grand Canyon as if you were in a helicopter! Zoom down close & see the individual rapids with their white water.... Or tour round Mt Fuji in Japan. Or Uluru (Ayer's Rock). Or down a main city street! And you can click on the street & get its name! Tall skyscrapers don't image all that well in 3-d, as it must have been hard to get really good stereo images of them from space, but the effect is there. A scale gives your 'nominal' altitude for any particular view. If you get lost in your orientation, just click on the North button to restore that orientation. You'll see as you zoom in that some areas are darker than others - these are the areas with the most detailed imaging. (I'm sure that all areas will eventually be imaged to the same scale....) Then zoom out, and 'fly' off to somewhere else. Must have a look at Turkey for the eclipse viewing...... If your house lies in one of the areas that has been well imaged, look - you might see your own car in your own driveway..... Fantastic - and a bit scary! Clear skies, Terry Moseley
