I pulled this of the internet, "annular eclipses, which do not result in the sky getting dark are just as productive in the Baily's Beads department. At the north graze zone, large beads are seen (just the opposite from a total solar eclipse) and from the south graze zone, tinier beads will be detected. If you have ever tried to capture 2nd and 3rd contacts of an annular eclipse from the centerline, you probably have been very disappointed. Those contacts are ill defined and while beads can be seen, they are generally so short-lived and hard to isolate that photos do not do them justice. But just move up into the graze zone and you will have an entirely wonderful surprise and still be contributing to the solar radius definition program of IOTA. The beads are just aas prolonged as during a total eclipse and even though the central eclipse does not take on a Bull's Eye effect as seen at the center, central eclipse is still just as impressive!" moral of the story anywhere within the "zone" will be worthwhile and different things are visible in north and south "graze zones".
