Bright Blue light flashed in sky, left small smoke puff. No sound.

Sitting outside in Northwest Bakersfield, clear night, just happened to look up as an intense bright blue light in the sky about 200 yards up, flashed, burned out and left a small puff of smoke behind, which quickly dissipated. Absolutely no sound before, during or after flash. Initial thought was that it may have been a strange firework, or unusual rocket. But that theory was not plausible, being as no sound proceeded or accompanied it. It may have also been witnessed by an aircraft traveling south but at incredibly high altitude.
