Possible nova is a cataclysmic variable

Hi,

 

accroding to VSNET 17327 this new star is acataclysmic variable in outburst. I have observed it last nigth and am presently analysing the data.

 

PNV J17292916+0054043: likely new WZ Sge-type dwarf nova

   Maeda-san has reported photometric observations.
The data showed modulations resembling early superhumps.
According to Ayani-san, this object has been spectroscopically
confirmed to be a dwarf nova.  He II was also in emission,
which is sometimes seen in WZ Sge-type dwarf novae
in the early stage.  Further observations are highly requested.

Regards,

Josch (HMB)
