This was observed at the Headlands International Dark Sky Park. My wife Jill 1st observed the event. Besides us, one employee was present to see the event as he was putting away the telescopes from his chat. He said he has never seen one so large and bright in his life. This was the second event to happen in succession. There was a small item that fell in 5 minutes before this one wad observed that broke apart on the same trajectory and same angle.
