I'm curious to know how the time of the Solstice is determined.
I found which hour the Sun dropped to S 23d 26.1min Declination- 12/21/14 at 16hrs GMT and then began the rise back North- 12/22/14 at 6hrs GMT.
The number of hours between those hours (14 hours) was divided by 2 and added (or subtracted) to one of the hours to obtain a time of 23:00:00 on 12/21/2014.
Using Peter Hakel's, sun.xls spreadsheet I also established GHA at 180d on the same date thinking that might be reference point and got GMT 23:58:16.5
Any ideas what to do?
