Equinox Sunset

Today is the equinox which means the day was close to 12 hours long (atmospheric refraction adds a few minutes…check the length of today for your city!) It was also a nice evening in Tucson as the first cold front of the season moved through. A nice night to photograph sunset. First a wide shot of the setting Sun.

As the Sun set, the colors started to change.

Culminating with a nice green flash that was easily visible to the naked eye as well.
