Description

2020 solstice annular solar eclipse in Chiayi city, Taiwan.

First contact 14:49, annular 16:14, fourth contact 17:25.

With a fixed exposure condition w/ and w/o thousand oaks filter, sky brightness at eclipse max is seen even darker than that at sunset.

Also, with fixed coverage percentage interval (3.5%) and faster and faster lunar limb moving, the two adjacent sun positions get more and more close during setting.
