"A fireball is just a piece of material burning up in the earth's atmosphere, it's just a very bright shooting star," he added.

Just saw the whole #sky light up looking North from #Cork Like #lightning only none on radar?? What gives?? #Meteor? #Fireball? #Explosion?"We'll produce a report seeing where it landed, see if any of it survived. The last time we were successful was in 1999, it was found in Carlow. The pieces were so small, you could fit them into a mug. A collector from Scotland bought it and he was later selling pieces of it for 50 times the value of gold," Mr Moore said.
