Astronomy Ireland says a major fireball was spotted over Ireland at around 6pm this evening.
It says the rock from space was seen blazing in the air by people all over the country.
There are reports that the fireball has landed in a field near Crimlin in Co Cavan.
Astronomy Ireland says it is unlikely to have injured anyone as it would have slowed down when it hit the atmosphere.
Valentia Coastguard said it has had reports of sightings from people living in Mullingar, Limerick, Ballybunion and Bantry.
