I am trying to find the declination at the horizon in the east at a particular latitude.(adsbygoogle = window.adsbygoogle || []).push({});

The equation is:

delta = asin(sin(lat)*sin(Alt) - cos(lat)*cos(Alt)*cos(Azi))

where Azi is the azimuth and is equal to 90 degrees in the eastern most direction.

Alt is the Altitude and is equal to 0 degrees at the horizon.

From this equation delta is always equal to 0 but intuitively the horizon plane changes with the latitude.

Could this equation be misinterpreted?
