I am trying to write a program for my programmable calculator to calculate elevation / azimuth of an object (for my location and time) given Right Ascension and Declination.

I have a formula that requires the Greenwich Hour Angle of the Equinox at Jan 1, 2007 and I cannot seem to work out how to obtain it. Any clues?

If not does anyone have another formula?

Thanks in advance.

Regards

Peter
