Coast Geodetic
circumpolar stars declination?
The Damavand Mountain is located at the North part of Iran, in south coast of
Caspian Sea. Consider an observer standing on the Damavand mountaintop (latitude =
35° 57′ N; longitude = 52° 6′ E; altitude 5.6 x10^3m
from the mean sea level) and looking at
the sky over the Caspian Sea. What is the minimum declination for a star, to be seen
marginally circumpolar for this observer. Geodetic radius of the Earth at this latitude
is 6370.8 ݇݉km. Surface level of the Caspian Sea is approximately equal to the mean sea level
i know the condition of a star being circumpolar is that it’s latitude should be greater than declination? is it only applicable to altitude=0m or with all altitudes?
plz give me some initial guidelines to solve it out….
Hi. Kind of a trick question because the atmospheric refraction near the horizon allows stars to be seen below the horizon by half a degree or so,
