Special Notice #245: Outburst of SV Ari

Outburst of SV Ari

August 2, 2011

SV Ari, a suspected WZ Sge star, has gone into outburst.  Rod Stubbings posted a 15.0 magnitude estimate on 110802.788 that has been confirmed by Gianluca Masi.  Gary Poyner says:

"Discovered by M & G Wolf on Heidelberg plates taken in November 1905 at mag 12.0p.  Kimpel & Jansch reported a possible sighting in September 1943, but this was not confirmed.  Nothing has been seen since."

Located at 03 25 03.34 +19 49 52.9 J2000, SV Ari has a good BV sequence and so is an excellent target for CCD and visual observers alike.  As usual, early photometry is needed; please take filtered time series observations with exposures long enough to reach S/N=50.

Clear Skies!
