At first i thought that i had seen a meteorite out of the corner of my eye. as i was telling my son about it and pointing out where i had seen it, a glowing light appeared like a short pulse then went dark. a few seconds later it lit up again then went dark. this pattern continued on for approximately three to for minutes, we were able to anticipate it's next location because the pulse was happening in regular intervals .I first saw it from my perspective over palos verdes and it traveled in a direction that took it over down town los angeles. the object emitted two very bright flashes as it seemed to zoom off.
