Full Description & Details
What I saw was a bright yellow/orange light going from West to East, about 40 degrees above the South horizon. Then, I saw silver 'sparkles' trailing it for a minute, then nothing, then a puff of smoke with smoke ring, again, yellow light trailing smoke trail and finally a red light that faded to nothing. TURNS OUT THAT IT WAS A LAUNCH OF A MINOTAUR ROCKET FROM VANDENBERG AIR FORCE BASE, LAUNCHED AT 9:41 PM PDT. Very cool not knowing what it was, very cool to find I witnessed a rocket launch just up the coast.

Can sighting be explained as any conventional man-made or natural object?
yes, rocket launch from Vandenberg AFB

Reported Sighting? No
