This multi-flame picture shows you the progress of Annular solar eclipse on May 21, 2012.
The sun started to be eclipsed from its western rim at 6:20, annular eclipse could be observed from 7:34 to 7:39 for a bit shorter than 5 minutes.
And at the second and third contact of rims of the sun and moon, the Baily's beads could be detected.
In that day, the solar surface included three medium-scaled sunspot groups.
