Scientific paper

V358 Lyr, a likely WZ Sge variable, is undergoing a rare outburst, at V = 15.92 +/- 0.03 on 2008 Nov. 23.082 UT. The only known outburst was in 1965, as reported by Hoffmeister (1967, AN 289, 205). At that time, two photographic plates gave magnitudes of 16.42 and 17.31. AAVSO reports over the past year show fainter-than limits have typically been around V < 17.5. Henden gives limiting magnitudes from USNO-Flagstaff observations in September and October 2008 at V < 22.2 and < 22.5, respectively, giving a minimum outburst amplitude of 6.6 magnitudes. BVRI data from T. Krajci indicate the color is blue, as expected for a CV outburst. Time series photometry and visual monitoring are requested. Observations should be submitted to the AAVSO International Database.
