[vsnet-alert 5037] 1432-0033 is a new UGSU dwarf nova

["Tonny Vanmunster" <Tonny.Vanmunster@advalvas.be>]

Dear colleagues,

I'm observing the dwarf nova 1432-0033 in response to the recent outburst reported by R. Stubbings (VSNET-ALERT 5030), using the 0.35-m f/6.3 telescope with unfiltered ST-7 CCD of CBA Belgium Observatory. Also running my "real-time" light curve generator, allowing on-the-fly CCD data reduction and light curve visualisation.

The light curve clearly shows a superhump-like profile with an amplitude of about 0.6 mag. It's very difficult to determine the period of the signal (given the noise due to the low altitude of the object). A guess, looking at the light curve on screen, yields a value of approx. 0.07 d.

In Astrophys. J. Sup. 78, 409, 1992, Berg et al. mentioned this object as an emission-line CV, with a "resemblance to HT Cas and U Gem".   The object is located at 14h32m25.88s, -00d33'00".9 (J2000), with a reported quiescent magnitude of 18.5

I'll continue monitoring this object as long as possibe (but already getting very low now). Assistance from other observatories would be appreciated.

Best regards,
Tonny
