DDE 35: more likely a polar
This object was classified as an SU UMa star based on
superhump detection (vsnet-alert 24074). These humps,
however, were seen only on two nights (2020 Mar. 16 and 18)
and no humps were apparent on Mar. 19.
The ZTF data show distinct high and low states unlike
an SU UMa star (currently in bright state starting from
late 2021). The magnitude (around 16) in 2020 Mar. was
too faint (M_V=+6.6) for a superoutburst. The behavior
suggests that the object is likely a polar. I have not
been able to detect an orbital period in the ZTF data.
ASASSN-13bz: SU UMa star (or even WZ Sge)
Itoh-san detected superhumps on Dec. 3 (amplitude 0.12 mag).
The period from single-night baseline is 0.059(1) d.
I suspected this object to be an SS Cyg star based on
the initial fading rate (0.2-0.4 mag/d) and the lack of
superhumps, but this may have been a viscous decay phase
of a WZ Sge star (considering the rarity of outbursts).
Early superhumps may have not been present simply based on
a low inclination.
CRTS J220449.8+054852 superhump period
Tonny Vanmunster and Itoh-san have reported observations.
The superhump period from these observations was
0.0948(1) d, slightly shorter than reported in
[vsnet-alert 27150]. Large superhump amplitude.
