This report from several years ago (March 2009) has 2 large fireballs in the atmosphere over the East Coast at almost the same time of year - coincidence, but still very curious. Feb 2011 has similar stories on the East Coast here and missing the Earth here. It appears that it’s not uncommon over the East Coast or to have large fireballs hitting the states at the same time.
The past 10 days have seen 2 extremely bright fireballs over the East Coast of the US. Both fireballs also were accompanied by loud sonic booms.
The latest meteor occurred on Sunday night, March 29, at ~9:50 EDT. Observed from Pennsylvania to North Carolina, the fireball seems to have ended over the Norfolk/Virginia Beach area of southeast Virginia. A loud noise similar to an aircraft sonic boom or distant thunder was heard and felt ~2 minutes after the fireball last disrupted.
