2008CBET.1582....1H

A. Henden, AAVSO, reports that this variable has been found to be in outburst at mag 16.1 by J. Shears (Bunbury, U.K.) and G. Poyner (Birmingham, U.K.) from a Bradford Robotic Telescope unfiltered image taken on Nov. 22.917 UT; the position for V358 Lyr was measured to be R.A. = 18h59m32s.99, Decl. = +42o24'12".0 (equinox 2000.0). A confirming unfiltered image taken by S. Dvorak (Clermont, FL, U.S.A.) on Nov. 22.98 yields mag 16.1 and position end figures 32s.97, 11".7. T. Krajci (Cloudcroft, NM, U.S.A.) reports V = 15.92 ± 0.03 on Nov. 23.082 (average of 29 V-band images, with no obvious brightening or fading over the interval; color blue, as expected for a cataclysmic-variable outburst; position end figures 32s.96, 12".0). This is a likely WZ Sge-type variable. The only known outburst was in 1965, as reported by Hoffmeister (1967, A.N. 289, 205). At that time, two photographic plates gave magnitudes of 16.42 and 17.31. Antipin et al. (2004, IBVS 5544) looked at the original plate material and revised Hoffmeister's coordinates with measured end figures 32s.95, 12".3; Antipin et al. checked 30 years of Moscow photographic plates and found no other outburst. Henden gives limiting V magnitudes from USNO/Flagstaff observations: 2004 Sept. 3, [22.2; Oct. 15, [22.5. This gives a minimum outburst amplitude of 6.6 magnitudes.
