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 Charts for VY Aqr may be plotted with VSP: http://www.aavso.org/observing/charts/vsp/index.html?pickname=VY%20Aqr This AAVSO Special Notice was prepared by Matthew Templeton. --------------------------------------------------- SUBMIT OBSERVATIONS TO THE AAVSO Information on submitting observations to the AAVSO may be found at: http://www.aavso.org/observing/submit/ SPECIAL NOTICE ARCHIVE AND SUBSCRIPTION INFORMATION A Special Notice archive is available at the following URL: http://www.aavso.org/publications/specialnotice/ Subscribing and Unsubscribing may be done at the following URL: http://www.aavso.org/publications/email/
