I'm not sure if this is the correct part of the forum, so please move if neccessary.
For those interested, Asteroid 2012 DA14 is going to fly past the Earth at 17,000 miles tonight (which is closer than the moon at 25,000 miles and even some of our GPS satellites). It is about the size of an Olympic swimming pool, so will be difficult to see without some good binoculars or a small telescope, but there are apparently going to be clear skies across most of the UK so we should be able to see it in the east from about 8:00PM.
For a chart of where it will be at what time and further information see here:
