Geocenteric Equatorial Coordinates of the Sun

  1. I'm rather new here so please forgive me if this is answered somewhere else, but I was unable to find it while searching around.

    For some calculations I'm looking to perform I need to know the geocentric equatorial coordinates of the sun on a given date. However, the only place I know they are available available is in an astronomical almanac. Since I am unable to afford a copy of it every year I was wondering if there was another source that anyone knows of where I could find this same information. I see that there is so much information freely available online from NASA and other organizations, but I'm unable to find this specific information for some reason. Perhaps I will end up needing to calculate it myself? If someone could point me in a good direction that would be great.

    Thanks
