A Meteor Shower from Comet 103P Hartley?
Meteors are typically very small, material smaller than a grain of sand, a typical meteor burns up in the atmosphere.
Bright fireballs which can be seen in daylight are larger, around pebble size or a bit bigger. These can survive re-entry, but around 300 Km above the earth they are now falling slowly enough that the "re-entry burn" disappears. So yur meteor may have hit, but you wouldn't see it, and finding it would be a non trivial task.
because i was site surfing and i found nothing about a warning of the fireball.
thank you for your answer, i hope the collision doesn't make a big impact.
