Hi Robynne, Osteopathy is ruled by the asteroid STILL. For the ephemeris for STILL go to....www.true-node.com/eph1.
Type in the asteroid name STILL, also type in the date you want and you will get its location for a full month.
Find where it was at your birth then add your age now and this gives your current Solar Arc.
