Astronomers are calling for help in finding a meteorite that is believed to have landed in the Ireland or the UK.
Reports of a massive fireball in the sky in the early hours of Sunday morning could have been an object entering the atmosphere.

Anyone who saw it is being asked to go to www.astronomy.ie to list their sighting.
David Moore, Chairman of Astronomy Ireland, says meteorites can be incredibly valuable.
