Observing the eclipse

This was my 4th solar eclipse – all were different, all were exciting, but this one stood out as the friendliest of them all.

On August 11th 1999 on a residential street in Inverness, by chance, two strangers shared with me their welding masks*, revealing my first partial eclipse. I was hooked! The second was the July 11th 2010 total eclipse viewed from Hao, an atoll in the South Pacific. Atoll idyllic; latrines less so… Total darkness was followed by the diamond ring and Baily’s Beads – awesome! The third eclipse was viewed from Bryce Canyon U.S.A. 20th May 2012 and was where I first made my “Blue Peter” camera solar adaptor for the annular eclipse. Fortunately the eclipse was more impressive than the adaptor, and the adaptor did its

*Please note: only welding glass shade 14 or above is safe for solar viewing – if in doubt, don’t risk it!

Which brings us to Edinburgh – outside the Scottish Parliament, March 20th 2015 for a partial solar eclipse. My two previous eclipses had been spent alongside dedicated eclipse chasers. This one was spent with hundreds of the general public – all keen to view the eclipse, largely without equipment, but it was encouraging to note that some had made very effective pin-hole cameras.

Solar Glasses

Eclipse glasses are one of the easiest and cheapest methods of viewing an eclipse. Baader film eclipse glasses show a white sun and mylar (left, centre) ones a warm orange-yellow. My collection of glasses were handed round from person to person, nationality to nationality – it was a truly international gathering – until the cardboard of the glasses was limp but the glasses still effective. The camera adaptor was also very much in demand, and I was fortunate that it was borrowed by Priyanka Lele who produced some lovely images.

Solar Panels

Coffee was kindly brought to me by Alison and friend who were just as hooked on the eclipse as I had been when seeing it for the first time. “ Awesome”, “Incredible”, “Can’t believe the eclipse is going on and yet the sun seems the same” – quotes from bystanders, the last without solar glasses. Everything at that moment did seem as normal to the average bystander. As “totality” was reached it grew darker, the birds stopped singing and returned to the trees and those at home with solar panels noticed that their electricity generation dropped to zero.

The increasing cloud cover meant that the final phase could be viewed with the naked eye and was appreciated by many of the new-comers.

Finally the ASE participants gathered for a commemorative photo (see initial eclipse event report) followed by Sean’s welcome treat of coffee and eats in the Scottish Parliament.

A wonderful solar event to witness on the streets of Edinburgh in relative warmth, certainly with a very warm welcome from the general public. My personal thanks to all the members of the ASE present, especially Rachel, Ken and Sean for organising the event, not forgetting Alan Pickup for checking that Arthur’s Seat would not get in the way! My thanks also go to Karl, Dorothy and Sean for subsidising my parking – I will pay you back. Finally, thank you Geraldine for your enthusiasm, and for carrying my gear.
