Abstract
We summarise our optical monitoring program of VY Scl stars with the SMARTS telescopes, and triggered X-ray as well as optical observations after/during state transitions of V504 Cen and VY Scl.
Based partially on CNTAC programs 04B-0086, 05A-0004, 05B-0209, 06A-0099, 06B-0250, 07A-0384, 07B-0054, 08A-0026, 08B-0056, 09A-0025, as well as ESO DDT 276.D-5040 and 277.D-5034.
