This year the Orinids meteor shower peaks in the predawn skies of October 2st. Orion will be in the south around 4:30am BST an hour after the Moon has set and several hours before Sunrise. The meteors can appear in any part of the sky, but if you trace them back they will appear to originate from the constellation of Orion. For the best views look to the sky about 45 degrees on either side of the constellation from a dark sky location.
The meteors are caused by the Earth moving through the trail of debris left by Comet Halley.
