ABSTRACT

We measured the proper motion of the components of Herbig-Haro object HH 224 embedded in the rho Ophiuchi cloud core using two epochs of [S II] imaging with a 17-year baseline. Our analysis finds the direction of HH 224N to be consistent with the other components of HH 224S suggesting HH 224S and HH 224N are part of the same flow. We discuss possible driving sources.
