ASASSN-22fk: likely an SU UMa-type dwarf nova
ASASSN-22fk (=ZTF22aafasmd https://lasair.roe.ac.uk/object/ZTF22aafasmd/) was found on 8th April as a CV candidate by ASAS-SN team. On 9th April, we, Kyoto Univ. obs. detected probable superhumps with a period of 0.0596(5) d and an amplitude of 0.2 mags. Thus, ASASSN-22fk is likely an SU UMa-type dwarf nova.
Further observations are encouraged to determine its superhump period and evolution.
Best, Yusuke
