Sleeping and woke up around 3:15am. at 11:30am i reviewed the cctv security camera to verify if low motion detection setting recorded activity from the night sky. from the timeline there were 3 video events recorded from the night. at 2:15am-2:21am pdt there was a bright flash of light making night into day. the video recording of the flash of light could be inaccurate from the ccd sensor overexposing the bright flash of light from the sky. if there was a noise beyond 80db i should have heard it. the camera would have showed an alert on the timeline. the houses became clearly visible in great detail from the intensity of light from the sky. it seems unlikely that the intensity of a flare from the sky or a transformer created the bright light. if it were lightning from the clouds the video of entire sky from darkness to daylight should not appear that intense. my thoughts. the light may have been off the coast of the pacific ocean or within the san francisco bay. i wondered if it may be similar to the shag harbour incident of nova scotia. the flash of light happened for a duration of 1 second or 1.5 seconds.
