My mum just reminded me that this weekend sees the maximum of the Perseid meteor shower. What this means, to anyone who doesn't know astronomy, is that, clear skies permitting, it's the biggest, brightest and best meteor shower that we get here in British skies.
for more info, and where in the sky to look, check out this BBC article:

Sounds like the maximum is actually tomorrow night, but it should be happeneing all weekend and for the start of next week as well. So, if you happen to be out after dark, have a look.
