Hi! All, the group has gone very quiet lately so here is a quest !! I have a programm that calculates for me the Suns position but to do so it requires the mean longitude of the perigee of the Sun. I have an old equation that based on epoch 1900 and allows me to calculate the value for Jan 0 for any year and would like to be able to do so from Jan 0 2000 Thanks for your indulgence
