(fwd) 2QZ J021927.9-304545: yet another ugsu star

   The outburst pattern and superhump period look similar to those of DH Aql
(cf. IBVS 4227, Nogami and Kato 1995 and historical light curves)

Hi,

with the outburst ongoing for at least 48 hours, 2dF (QZ) J021927-3045 was 
observed over more than two hours continuously at CBA Pretoria using 15sec 
cycles.

Differential (unfiltered) photometry on the images clearly shows a smooth 
modulation with a typical ugsu amplitude of 0.25 magnitude. The s/hump 
period is estimated to be around 0.085d (+/- 0.01d). The mean magnitude is 
12.0CR, conveniently bright.

Further observations are intended.

This is a very suitable target for Southern CBA observers, following the 
RXS 1730-05 run. It will give a much nicer light curve though.. (sorry 
Joe).
There is a convenient comparison star @ 021905.5-304335, some 4' WNW of V. 
It's 12.5R (13.1V).

Regards,

Berto
