ASASSN-21br: short superhump period

Josch Hambsch and Berto Monard reported time-resolved observation of
ASASSN-21br.
The PDM period analysis yields a single-peak variation with the amplitude
of 0.04 mag and the period of 0.0261(2), likely an ordinary superhump.

Therefore, ASASSN-21br is likely a superoutburst from an AM CVn-type star.
Time-resolved observations are strongly encouraged for southern observers!
