ASASSN-19ax: possible superhump
Kiyota-san reported observations. The object showed 0.3-mag variation resembling a superhump. The length of observation was not sufficient to record a full cycle. The period (if the variation is periodic) appears to be longer than 2 hr and the object could be an SU UMa star above the period gap. Further observations are strongly encouraged.
