Not normal
Meteor hunters say they have found two more remnants of the streaking fireball that lit up California skies last month.

The latest find - reported on Thursday - was also in the San Francisco Bay area city of Novato and brings the total number of chunks of rock that fell from the Oct. 17 meteor explosion to four. The meteorites are known as metal chondrites because they contain microscopic metal particles called chondrules.

The exploding streak was especially visible over the San Francisco Bay Area and other parts of Northern California, with reports of a bright fireball and loud boom from Santa Cruz County to Mendocino County.

Warm temperatures and cloud-free skies made the bright light more visible.
