It got a little darker. We noticed that, and how odd it felt for the shadows to be the wrong length for that amount of darkness. It wasn't darker than a thundery day, but of course you don't have shadows on a thundery day.
Both our viewing techniques worked.
The mirror - taping over all but a 1cm square of a small hand-held mirror, and reflecting the image onto a wall. We taped a piece of white paper to the wall to make it clearer.
Simple pin-hole camera. Just two pieces of white paper, one with a pen-prick hole in it, allowing just enough light in to see the crescent shape.
At the last minute I remembered that I viewed the one at Stonehenge through the video camera, so I viewed it through there as well. That was exceedingly pretty, with sun rays streaking through a blue sky, but not in the least eclipse-like! I guess we were just too far north after all.
Now we're watching it on TV and seeing what we missed out on!
