misheyakir10Point2Degrees
This method returns misheyakir based on the position of the sun when it is 10.2˚ below geometric zenith (90). This calculation is used for calculating misheyakir according to some opinions. This calculation is based on the position of the sun 45 minutes before sunrise in Jerusalem around the equinox which calculates to 10.2 below geometric zenith.
