If, like me, cloud cover prevented any sightings of the annual Perseids meteor shower last night there’s another chance to see them tonight – although the weather’s not looking any more promising at the minute. Astronomy Ireland have their Perseids Watch underway too. But in the worse case scenario you can, as the Guardian notes, follow the Perseids meteor watch on Twitter, organised by the Newbury Astronomical Society and the International Year of Astronomy 2009, where there will be, and have been, links to images of the meteors seen by observers around the world. And one twitterer there hopes to provide an online live-broadcast of the night sky up on a hill (Mam Tor) in Derbyshire [from approx 11pm BST]. Update Clearer skies than expected, but only brightest constellations visible. Still, there are meteors to be seen out there.
