Would observing an eclipse closer to the center line of totality reduce the duration and 'intensity' of Bailey's Beads ??
I'm still amazed at the difference in them I saw between '79 and '17 and I'm trying to noodle out the why of it.
Since bailey's beads form when, from the perspective of the viewer, parts of the limb of the sun exactly coincides with parts of the limb of the moon, so rugged topography on the limb of the moon would interrupt sunlight into beads, it stands to reason bailey's beads would be most long lasting and intense from where the limp of the sun would coincide with longest stretch of the limb of the moon for the longest period.
It appears to me this would occur right on the edge of totality, you should see almost a half circle of bailey's beads right through the entire totality.
Another difference between two eclipse could be difference in relative apparent size of the sun and moon. Bailey's beads ought to be more intense and widespread during those eslipses where the visual size of the moon is exactly the same as the visual size of the sun, or a eclipse that is exactly at the boundary between an annular and a total eclipse. This way you should see a circular string of bailey's beads for just a instant. Of course I don't know if there is such a eclipse in my lifetime.
