[vsnet-alert 15220] CSS 100317:041637+292806: possible superhumps?

[Gianluca Masi]

Dear Colleagues,

we have finished about 5 hours of time resolved photometry on
this star, remotely using the 17" robotic unit part of the Virtual telescope 
Project in Italy.

The source was about at mag. 16.5, while the sky was quite bright because of the 
full Moon. The lightcurve shows a modulation, about 0.15 mag large, suggesting 
possible superhumps.

We estimated a period for it, finding a candidate of 1.6 hours.

Data were sent to Kyoto for analysis.

Regards,
Gianluca Masi
