i was standing in a view area that overlooks the sea on us 101 southbound in gaviota california. i was looking through some very powerful new binoculars i carry with me in my big rig. the sun had just set, but their was still a lot of light. within 10 minutes i had spotted 3 prides of dolphins, and a female with a new born. i set my binoculars on top of the ones mounted there by the state. using the state's rotating mount, i was really enjoying ease of viewing the mother dolphin teaching her newborn how to navigate in the kelp. as i was gazing down at them, a matalic silver ball, about the size of a softball, crossed my view only 10 to 15 feet above the dolphins i was looking at. i tracked it with ease, and saw it clearly for 6 seconds as it flew southwest out to sea. it slowed as it came into view, to about 25mph. then soon as it passed the dolphins, it accelerated quickly to about 50mph and gained only a few feet in altitude, before it vanished in the wind blown mist off the sea. i yelled out loud, "show me again please!" and stood their for another hour just to see if it would.
