So, latitude zero, declination zero, azimuth at sunrise = 090°. That figures. It is also confirmed by the Amplitude Tables. The difference between amplitude and declination gradually increases as declination increases although interestingly the percentage difference for at a particular latitude stays about the same for any declination. E,g. at 23.5° declination and 23.5° latitude the difference is 2.3° or 0.98%. At 10 declination and 23.5° latitude it’s 0.95° or 0.95%. DaveP
