Bright new dwarf nova (or nova?) in Sgr: PNV J17522579-2126215

Dear Folks,

There has been a new transient in Sgr reporten in the CBET TOCP home page: PNV J17522579-2126215

The latest data show it has brightened up to 8.9R.

The medium-resolution optical spectrogram obtained with the 0.5m RC telescope of the Gothard Observatory by L. Kiss et al. show lack of strong emission lines (private communication). So this may be a dwarf nova, not a nova? Interesting...
