Bearing in mind I know nothing of comets, I initially thought it might be one. I googled for other sightings and haven't found anything as yet. I did find Asteroid 2011MD but that wasn't due to go past till 27 June 2011. What's your opinion? One of the above? Meteorite? Some kind of UFO? We're stumped and really surprised there's been nothing in the media about it.
