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
