V803 Centauri - April 1997 - CBA

This is a light curve of V803 Cen, as synthesized from observations in South Africa (J. Patterson), Chile (J. Kemp), New Zealand (S. Walker), and Australia (P. McGee in Adelaide and G. Garradd in Loomberah). The period is 23.7±0.2 hr. The true speed demon among the dwarf novae!
