That is very surprising! How cool for you that you got to witness it and get some great shots too!
At first glance this appears similar to my observation at www.ispot.org.uk/node/321214, well done for getting a picture.
Thank you both for your comments. Yes it sounds similar to your observation Ray.
It was very difficult to capture a decent picture with the heavy lens, the ones I have posted are the best, I think I only managed to get one actually in focus!
