Red =Sun position - coordinates (already done)
Blue =Sun position - coordinates (future)
Green =Actual path of the sun, declination exceeds the latitude in the year 2 times.
Sun disc =Sun disc enlarged by the fold of 4,9 (linear enlarged) excessively large, serves only a better visualization, actual size of the mean sun disc 0,5338° +/- 1,7% during the year, plus the astronomical refraction at approximately 0,6°.
Attention All times are local times (LT), note time difference in countries with summer time. For example, for Germany in the summer months: Add +1 hour to the local time.

Calculation formula for Lambda according to "Jean Meeus, Astronomical Algorithms, Willmann-Bell, Richmond 2000". Calculation of the mean star time Sternzeit with complete formula of the revision from 1984.

All times are local times (LT), note time difference in countries with summer time! For example, for Germany in the summer months: Add +1 hour to the local time. Times for twilight: Civil twilight, center of the sun disc is -6° below the true horizon. Times for sunrise and sunset: Top edge of the sun disc reaches or is below of the true horizon.
