[Aavso-photometry] Optical transient OT_J021110.2+171624

[Tom Krajci]

I've started a time-series, 30-second exposures, on this target.  I should
be able to get 4 hours coverage...weather looks good for the evening.

novanature confirmed


Dear colleagues,

A very quick message (I leave on holiday in a few hours) to inform you that
subsequent observations of  OT_J021110.2+171624 by CBA observer Tom Krajci
(obtained on JD +497.5) clearly confirm the SU UMa-type nature of this dwarf
nova. I will publish a detailed analysis in about a week from now, but Tom's
observations show full-grown superhumps with an amplitude of 0.35 mag and a
period close to 0.082 +/- 0.002 d.

Best regards,
Tonny Vanmunster
