Mercury transit photos
Attached are images of Mercury just beginning its transit of the sun soon after 08:12 this morning. They were taken with
a telescope at the University of Canterbury's Mt John Observatory, Lake Tekapo.
The pictures show Mercury as a tiny round dot, edging onto the sun. The large object below it, in these photos, is a
sunspot: a cool region on the sun's surface.
The Mercury disk is very small with a diameter around 1/200th of the sun's disk. So on an 8-inch, 200-mm image of the
sun Mercury appears 1 mm across.
