Scientific paper

The proper motion of optical filaments associated with the supernova remnant of 1006 (LUPUS) is studied by intercomparing discovery plates obtained in 1976 to CTIO 4 m plates taken in 1981. Results show that the optical remnant is expanding with a mean proper motion of expansion of 0.39 + or - 0.06 arcsec/yr. Results of a comparison with the value of 0.33 arcsec/yr expected for a Sedov solution, indicates that the remnant is presently in the adiabatic phase of its evolution.
