Where is the Sun straight up at the September Equinox?
When is the equinox?
- Time Zone Master gives 5:05 EDT September 23
Is the sun directly overhead at noon anywhere exactly at the time of equinox?
- No. Using local timezones the closest is 12:05 EAT in East Africa
What about using solar/sundial time, instead of timezone time?
- Yes there is a place, and here is how to find it:
Using our product Time Zone Master
1) Click any clock and go to the equinox page, you then click on the equinox time (5:05 EDT for my case for Ottawa)
2) Then go to the sidereal page it shows 9:12:28 GST (sidereal time)
3) The time difference to noon is 2h 47m 31s
4) Using a calculator, Multiply by 15 gives 41d 52m 45s E
5) Now open a new clock and enter Long 41d 52m 45s E and select equator
The result is near a town called Chisimayu in Somalia, near the Kenya border, where the sun will be straight overhead at solar noon, exactly at the time of the equinox
