Whats New?

The following was issued on November 4, 2002, as VSNET campaign circulation 1347 (reprinted with permission)


AW Sge (RA = 19h58m37s.11, Dec = +16d41'28".7) M. Simonsen detected an outburst of the poorly known SU UMa star, AW Sge at 14.4mag on October 31. The last recorded outburst (superoutburst) was in 2000 July (vsnet-campaign-dn 2946). The brightness suggested a superoutburst (vsnet-campaign-dn 2949). Observations by the Nyrola team, however, indicated a rather rapid decline at a rate of 0.9 mag/d (vsnet-campaign-dn 2955). On October 31, T. Vanmunster reported irregular modulations with an amplitude of about 0.3mag, which are not superhumps (vsnet-campaign-dn 2956, 2958, 2960). After the fading, a possible rebrightening to 17.2mag on November 3 was reported by D. Starkey (vsnet-campaign-dn 2951, 2954, 2969). Confirmations are urged.


 PU Per (RA = 02h42m16s.1, Dec = 35d40'46")

 M. Simonsen reported on November 1 that the SU UMa-type dwarf nova, PU Per is undergoing a rare, bright (14.7mag) outburst. The last reported outburst of PU Per occurred in 1998 September. Its large outburst amplitude and long recurrent time suggest that the object may be related to WZ Sge-type stars (vsnet-campaign-dn 2959). In the light curve taken by D. Starkey, small-amplitude variations are likely present, while there is no distinct superhumps (vsnet-campaign-dn 2962). The time-series observation by G. Billings on November 2 yields a light curve showing a rather rapid linear fading, with 0.1-mag fluctuations. T. Kato commented that, judging from the behavior up to now and the short-term variations, the outburst may be a normal outburst, or a precursor outburst of an expected superoutburst (vsnet-campaign-dn 2963, 2967). The object further faded by 1.5mag on November 3, which supports that the outburst is a normal one (vsnet-campaign-dn 2970).
