Abstract (from CDS):

We report optical observations of the VY Scl star BZ Cam during its previous optical low state in 1999/2000. We find drastic variations in the line profiles. Narrow-band imaging observations show that its nebula extends farther than previously known and seems to be composed of two components. We determine the [OIII] line intensity of BZ Cam's nebula to 4.8x10–13erg/cm2/s. We discover a proper motion of BZ Cam of 25±2mas/yr which together with the systemic radial velocity yields a space velocity of 125km/s. We re-interpret the nebula as being photo-ionized by hypothesized transient, luminous, supersoft X-ray emission during optical low states, and shaped by the transverse motion of BZ Cam.
