|EAAS Meeting report May 2004|
The evening kicked off with a very informative rundown on the history of past transits by founding member Alfie Snoddy. Alfie travelled back in time to 1639 when that transit was first predicted and observed by the little known Jeremiah Horrocks, now considered by historians to be the Father of English astronomy! More information about Jeremiah and the history of the Venus transits can be found on the Venus transit webpage.
He also explained the mechanics of transits, both Mercurial and Venusian, why they occur, how often do we see them, and what to look out for during the event.
Robert Hill (Armagh Planetarium) then gave an insight as to how our Society could get involved in various projects including one set up by the European Space Agency that includes millions of school children from Europe, Africa, Asia and Australia.
Mark and Nigel Stronge then spoke on how to capture the event for posterity. They discussed the checking of solar filters and the safety precautions that one should take while observing the transit or solar observing in general. Click here to read about safe solar observing techniques.
