ASASSN-24gm: new WZ Sge-type dwarf nova
South African Astronomical Observatory team and Josch Hambsch have reported the time-resolved observations of ASASSN-24gm. Observations on 12 Nov. at SAAO detected clear superhumps, ~16 d after its discovery by ASAS-SN on 27th Oct. The tentative superhumps period is 0.0602(1) d, while 1-d aliases are still possible.
Combining its short superhump period, large outburst amplitude of 8.4 mag, and long waiting time for superhump appearance, ASASSN-24gm is likely a new WZ Sge-type dwarf nova. Further observations are encouraged.
