The Sun has zero declination at the two equinoxes on March 21 and September 21 (approximately). At the autumn equinox in September it crosses the plane of the Earth's orbit from north to south, so its declination goes from positive to negative.

Does a star that is located 30 degrees north of the celestial equator have 30 degrees declination?

Yes. "Declination" on the celestial coordinate system is the counterpart of "latitude" on the terrestrial coordinate system. Positive and negative declination correspond respectively to north and south latitude.


Calculate the magnetic bearing from a true bearing of 180 degree from a map with declination of 8 degrees east?

To calculate the magnetic bearing, you would subtract the declination from the true bearing if the declination is east, or add the declination if the declination is west. In this case, since the declination is 8 degrees east, you would subtract the declination from the true bearing of 180 degrees. Magnetic bearing = True bearing - Declination Magnetic bearing = 180 degrees - 8 degrees Magnetic bearing = 172 degrees
