Alert Notice 386: Low state of VY Scl

October 2, 2008 : The cataclysmic variable VY Scl appears to have recently entered a low state according to observations recently submitted to the AAVSO. Javier Temprano reports positive detections of VY Scl at CV=17.46 on JD 2454730.46181 (2008 Sept 20.9618) and at CV=18.23 on JD 2454730.572 (2008 Sept 21.072). All other recent AAVSO and ASAS-3 (Pojmanski, G. 2002, Acta Astronomica 52, 397) observations indicate that VY Scl is below detectability limits. This is the first time VY Scl has been detected in a deep minimum in many years, comparable to the deep minimum observed by Cropper and Warner in 1983 (IAUC 3877). Observations of VY Scl, both visual and instrumental, are urgently requested beginning immediately, and continuing through this current episode.

VY Scl (AUID 000-BCR-581) is located at the following (J2000) coordinates:

RA: 23 29 00.50 , Dec: -29 46 46.0
