I'm pretty sure there's not just one database for meteor sightings, and i'm also not sure if you mean NEOs and/or fire balls and so on, so i think your best bet is probably to check out the thread
Near-Earth objects and close calls.
That link should take you to the last page and if you work your way backwards you'll find a some compiled info and analysis by users from the forum as well as links to external sites, like the American Meteor Society's
database.
