Autumnal equinox approaching

This is sorta/kinda kayaking related. Mainly just a reminder that the days are getting shorter very rapidly this time of year.

The autumnal equinox is technically the time when the sun crosses the celestial and terrestrial equator. It moves to a maximum elevation of 23.45 degrees above the equator at the summer solstice and - 23.45 at the winter solstice.

The actual moment of the autumnal equinox is Sept. 22nd at 10:44. Equinox means "equal night" - the length of day and night are equal (actually the length of day on Sept. 22nd is 12 hours, 9 minutes). The sun sets at 18:41 (6:41 PM) EDT.

We lose about 3 minutes of day time every day at this time of year, so it can quickly accumulate and take you by surprise if you're out paddling or biking or doing some outdoor activity.

Another little factoid is that the sun will set due west and rise due east at the equinoxes, as the fall progresses, it will set south of due east and south of due west and its maximum height will get lower. Also - bad news for people who suffer from seasonal affective disorder!
