Here
is a low-resolution video clip of the event. (670 kb)
The video starts a few seconds before the WWV time signal at 00:52:00
UT,
which can just be heard.
First disappearance occurs nearly 9 seconds after that time signal.
Watch as the star/asteroid combination dim to the magnitude of the
asteroid only.
Then the star reappears, disappears, and reappears in rapid succession.
This looks like a GRAZING occultation of an asteroid!
