Dan, Steve
Regarding the exact time of intersection: It requires a rather
interesting problem of simultaneously minimizing EOT and declination
between spring and fall dates. Fortunately I have a spread sheet that
implements the calculation of EOT to within a second or so and likewise

Hi Dan,
To me the value of the EQT at the intersection is an indication of the
asymmetry of the analemma caused by the difference between the solstice and
perihelion dates. The tilt of the earths axis is one parameter that def
curve intersection.

Hello,
Tomorrow the Sun will have reached the point of intersection in the
analemma 8-curve. How do you compute the exact time of intersection (i.e.
when both the hour angle and the solar declination match for two days)? And
does it have any special significance?
