ASASSN-21fr: new SU UMa-type (& possible WZ Sge-type) dwarf nova
Kyoto Univ. Obs., Tonny Vanmunster, and Tamás Tordai have reported
time-resolved observations of ASASSN-21fr.
Our observations on 21st April detected ordinary superhumps with the
amplitude of ~0.2 mag and the period of ~0.055 d, confirming ASASSN-21fr as
a SU UMa-type dwarf nova.
Moreover, as ASASSN-21fr was found on 13th April but no clear moderations
were observed until today, ASASSN-21fr is likely a low-inclination WZ
Sge-type dwarf nova.
Time-resolved observations are encouraged to establish the superhump period.
Best,
Yusuke
