ASASSN-16ga: new SU UMa-type dwarf nova
Josch Hambsch has reported observations on two nights.
Superhumps were apparent on Jan. 20 and 21.
The period will be determined as more observations become
available (relatively long).

ASASSN-V J202511.39+250535.3 large-amplitude dwarf nova state
According to Moriyama-san and ATLAS forced photometry
(Tonry et al. 2018; Shingles et al. 2021), this IW And star
has been showing large-amplitude dwarf nova outburst
(4 mag) since 2022 (dwarf nova state in 2021 with smaller
amplitudes).
