ASASSN-21lm: new SU UMa-type dwarf nova

The outburst of ASASSN-21lm (=ZTF21abhtieg) was detected by ASAS-SN team on
22nd June, with an amplitude of ~6 mag.
Tamás Tordai reported the observation for ASASSN-21lm on 28th June.
The light curve shows likely ordinary superhumps with the amplitude of ~0.2
mag and the period of ~0.06 d.
Therefore, ASASSN-21lm seems to be a new SU UMa-type dwarf nova.

Time-resolved observations are encouraged to determine the better superhump
period.
