A Systematic Search for Flickering in Southern Symbiotic Stars
Differential light curves of V648 Car with respect to a "virtual star" obtained by combining three comparison stars. The cadence of the observations is 112 s, and the maximum recorded amplitude amounts to 0.63 mag. Based on data obtained at the 1m Swope Telescope, Las Campanas Observatory, Chile (from Angeloni et al. 2012, ApJL, 2012, 756, 21A).
