Mortal as I am, I know that I am born for a day. But when I follow at my pleasure the serried multitude of the stars in their circular course, my feet no longer touch the earth - Ptolemy
Solar Eclipse Experience
The last time I witnessed a solar eclipse was in August 1999. I remember it was 95% totality and clear, I had a great view from my own back garden. Sixteen years on, in a different garden just around the corner, I again had a grandstand view of an 87-88% solar eclipse. I experienced the same drop in temperature and light level, and the birds fell silent. I managed to use a crystal to project rainbow-coloured eclipse shapes onto my white kitchen ceiling and photograph this as I don't own any spectacular camera equipment nor any solar filters!
The BBC's Stargazing Live programmes were very enjoyable and didn't just concentrate on the upcoming solar eclipse even though they had been timed to coincide with it. They had guest stars including the wonderfully amenable Edwin Eugene (Buzz) Aldrin, who at 85 had amazing recall of the historic day back in July 1969 when he and Neil Armstrong landed on the Moon. He was full of energy and seemed delighted to be on the programme, happily answering questions in the informal question and answer sessions following the two shows he appeared in. Buzz was heading home on the Friday - the day of the solar eclipse - and he tweeted that he'd be watching it from his plane. He said that he'd managed to visit his friend Prof Stephen Hawking and had enjoyed his visit to the UK as always, and we hope he makes many more such visits.
Another guest on Stargazing Live was The Sky At Night's Dr Chris Lintott who was requesting help from the zooites in the search for supernovae, the latest Citizen Science project. This was (hopefully) to culminate in a more accurate age of the Universe. One such supernova was detected and on the third night it was announced that the Universe is (probably) older than we had previously thought, at over 14 billion years. This had all been worked out on the back of an envelope which was passed around and much joked about! Further study is required for a more accurate estimation and if you would like to participate, you can check out Snapshot Supernova. I've already done my bit, and may do some more if time permits.
