[vsnet-alert 19049] ASASSN-15po: preliminary analysis

[Gianluca Masi]

Dear Colleagues,

I managed to cover this star by time-resolved photometry for almost 6 hours, 
remotely using the Virtual Telescope robotic facility. The sky was amazing.

The star was ~ mag. 14.3, unfiltered.

The resulting lightcurve clearly shows early superhumps with an estimated period 
of 1.20(6) hours and an amplitude of 0.07 mags. The star showed a slow fading 
trend during the run.

Further observations are encouraged to track the development of early superhumps 
and emerging, ordinary superhumps.

Data sent to Kyoto for analysis.

Best regards
