That day I tried to get a "live" video streaming, I looked and searched and searched.. got none. It was disappointing. From the photo (right frame), seems the passing was subtle (not so obvious, not so conspicuous) to naked eyes (or even small binoculars) ? It's strange that people didn't know whether eclipsing going to be full or ring type or concentric circle type or at different angle and no one knew how long it was going to last (some said 8 seconds, some said 15 seconds..). Seems there was no good data/prediction - neither on size of asterois nor angle (precise passing path) from various viewing locations in that narrow belt... Oh well..

Last night, the asteroid Leona passed in front of the red supergiant Betelgeuse, one of the brightest stars of the famous constellation Orion, but this was only visible from a very narrow corridor covering Asia, Europe and America. Such event is extremely rare for such a bright star: once in an astronomer lifetime!
Despite high clouds covering southern Spain, I clearly saw Betelgeuse darkening for about ten seconds from the Alicante area.
Betelgeuse is much larger than the Sun: placed at the center of the solar system, it would engulf the orbits of Mercury, Venus and Mars. Within 100,000 years (a very short time on the scale of the life of stars), it could explode in a supernova. Since Leona was not large enough to hide it completely, the occultation occurred as an annular eclipse and this is the reason why Betelgeuse did not disappear but only darkened.
