# The Sun’s position in the sky

@article{Jenkins2013TheSP, title={The Sun’s position in the sky}, author={Alejandro Jenkins}, journal={European Journal of Physics}, year={2013}, volume={34}, pages={633-652} }

We express the position of the Sun in the sky as a function of time and the observer?s geographic coordinates. Our method is based on applying rotation matrices to vectors describing points on the celestial sphere. We also derive direct expressions, as functions of date of the year and geographic latitude, for the duration of daylight, the maximum and minimum altitudes of the Sun, and the cardinal directions to sunrise and sunset. We discuss how to account for the eccentricity of the Earth?s… Expand

35 minute green flash observed at Little America on 16 October 1929: a retrospective study.

- Physics, Medicine

- 2015

The constraints placed on the observation by the Earth-Sun orbital kinematics are examined and it is found that the length of the observation cannot be explained solely by the slowness of the setting rate of the Sun, nor the time required just before the beginning of the Antarctic summer for the top of the sun to set, reach its relative minimum position at the horizon, and then rise back up again.
