AAVSO Special Notice #114

Rebrightening of the dwarf nova VY Aqr
July 22, 2008

Several observers have reported that the dwarf nova VY Aqr has
rebrightened since fading from its initial superoutburst.  Although
VY Aqr has been classified as a WZ Sge-type dwarf nova, previous
superoutburst rebrightenings have not been well-observed.  Continued
monitoring of VY Aqr for the next several weeks is strongly encouraged.
Both visual and CCD time-series observations are needed, the former
to track the overall light curve, and the latter to study superhumps
and short-term variability.  Both positive and fainter-than estimates
are valuable, so please continue to monitor VY Aqr if and when it
becomes faint again -- it may undergo further rebrightenings during
this outburst.

VY Aqr (AUID 000-BCN-520) is located at J2000 coordinates
RA: 21 12 09.20 , Dec: -08 49 36.5
