Thanks for all your comments David, Marc, Andrew & John, I appreciate them.
I am in a bit of a quandary at the moment, as 4 different astronomy applications indicate 4 differing locations of Phoebe.
I may have to visit the JPL Horizons website to obtain accurate positional data to solve these discrepancies.
My admiration for the discoverers of these faint objects has increased by leaps and bounds.
Cheers
Dennis
