[vsnet-alert 28205] DDE 196 (IPHAS J043920.40+500536.6): detection of early superhumps.
Dear Colleagues, I performed time-resolved photometry for DDE 196 = IPHAS J043920.40+500536.6, recently spotted in outburst (vsnet-alert 28201). I collected two runs, on 15 and 16 Aug. and their analysis reveals early superhumps. The target is right now at mag. 13.0 (unfiltered, R-mags for the reference stars from GAIA DR2). Data will be send to Kyoto for further analysis. Further observations are strongly encouraged. All the best Gianluca Masi
Dear Colleagues, using both my datasets, I obtain a preliminary period for the early superhumps of 1.19 +/- 0.01 hours. Regards Gianluca Il 16/08/26 04:41, Gianluca Masi via vsnet-alert ha scritto:
