Dear Colleagues,


I managed to make further time-resolved photometry of this transient, via the Virtual Telescope's robotic facility in Italy, covering it for 3.6 hours. Observations were unfiltered.

The source was about 0.5 mag. fainter than two nights ago, sitting at mag. 10.8 ( (R mags for the reference stars from Gaia DR1).


Despite bad seeing (high wind), I detected clear superhumps, with a full amplitude of 0.1 mag.


Using both the 22 and 24 Feb. data, I performed a period analysis, via PDM, getting an estimate for the period of Psh (h)= 1.545 +/- 0.009 hours.


Data will be sent to Kyoto for further analysis.


Best
Gianluca Masi
