If you fancy waiting up until after midnight or so, there promises to be a cracker of a meteor shower on display tonight.

"If we're lucky, on Sunday night and Monday morning we might see as many as 100 meteors an hour," said Dr Robert Massey from the UK's Royal Astronomical Society.
"But the usual caveat applies: you still need good weather."
The best viewing conditions will be where the sky is clearest and darkest. However, meteors should be visible, to a lesser degree, in cities despite light pollution and smog.
"You will see them almost wherever you are, so it's worth a look," Dr Massey added.
Both hemispheres will receive good views but the prime locations will be Western Europe and North America.
Watchers will get the best of the display from about 2200 BST (2100 GMT) on Sunday 12 August, which will peak just before sunrise on Monday 13 August.
