VW Tuc outburst observation
Dear Colleagues,
We have received VW Tuc time-series observations from Peter Nelson
and Bernard Heathcote. The data were taken on two nights (Jan. 3 and 4).
The object was fading linearly during this period. No apparent superhumps
were observed, suggesting that the object is an SS Cyg-type (UGSS) dwarf
nova. The mean decline rate was 0.4 mag/d, which implies a moderate
orbital period. Further analysis for short-period variation will be
undertaken. Further nightly (snapshot) observations are still encouraged
to fully describe the characteristics of the outburst of this poorly known
object.
We have also received several images, which will be later posted on
the VSNET website.
Regards,
Taichi Kato
