Can anyone advise me how to determine the times of GRS passage of the Jovian Central Meridian. Obviously I have the BAA Handbook with the details that it contains, however, what I think I am missing is the longitude of the GRS, or indeed any other prominent atmospeheric phenomena. I have the current value from this months’ copy of Astronomy Now, and very useful it has proved, but presumeably the longitude will vary with time; where can I find out this information (apart from hoping that Astronomy Now continue to publish it)?Many thanks.Martin Butcher
