61. See a cool astronomical phenomenon (eg a total eclipse, or the aurora borealis)
On March 3, 2007, there was a total eclipse of the moon visible from London. But it had been cloudy for ages so we sort of forgot. However, just before totality the clouds cleared. We didn't manage to get very far from the loom, though we were somewhere a bit darker than Walthamstow. Nevertheless, it was clear, and deep red, and we took some rubbish photos, and it was lots of fun. So this one is completed, even if total eclipses of the moon are not as cool as those of the sun.
