The Novato meteorite is an

Pacific Time on 17 October 2012. The falling bolide created a bright fireball and sonic booms and fragmented into smaller pieces as the intense friction of passing through the atmosphere heated it and absorbed its kinetic energy.[2] The meteoroid was about 35 centimeters (14 in) across.[3]

Meteorite

The first fragment of the meteorite (N01) was recovered by Lisa Webber on 20 October after reading a story in the San Francisco Chronicle that described the NASA/CAMS meteor trajectory predicting a fall area in the North Bay.[4] Lisa recalled hearing a sound on her roof the night of the meteor and went outside and located a 62 gram stone. Analysis of fragment N01 by Dr. Alan Rubin came back as a L6 breccia.[5]

The second fragment was found by Brien Cook on 22 October (66 grams) and the third fragment was found by Jason Utas on 27 October (79 grams).[1][6] The largest fragment recovered as of 5 November 2012 is N04 at 96 grams found by Robert Verish on 27 October.[7] A fifth stone (N05) weighing 24 grams was found by Jason Utas on November 2.[6] A sixth stone (N06) weighing 23.7 grams was found by the Kane family on November 11.[7] More massive 1 kilogram (2.2 lb) fragments may have fallen near Sonoma with any 10 kilograms (22 lb) fragments possibly falling near Yountville.[8]

This was the second significant meteorite in California in 2012, the first being the Sutter's Mill meteorite.
