Sometime around 11:00PM we saw what appeared to be three meteorites in formation flying just over the western horizon from south to north. Three in formation was strange, and these were a blue/green color behind a broken cloud cover. Approximately 3 to 5 seconds later, a single sighting of the same type was seen streaking from zenith to north. Both sightings lasted about two seconds each.
