ASASSNSP data shows quasi periodic oscillations and flares of UGZ/IW variable ASAS J071404+7004.3 well as fadings like to “anti-dwarf novae” VY type. It seems the star climbs up from fading right now.
Analysis of the IW And star ASAS J071404+7004.3
By autors’ opinion, the star does not belong to VY type: “The low state described by Inight et al. (2022) was not a true low state of a VY Scl star, but a dwarf nova-type state with increased outburst amplitudes… Typical low states of VY Scl stars lasts months to years and there are usually no strong sign of dwarf-nova outbursts during decline despite that the mass-transfer rates decrease… The fading episode in ASAS J071404+7004.3 was simply a dwarf nova phase with larger amplitudes (as in Z Cam stars) when the mass-transfer rate dropped slightly.”
So both episodes may be too short for VY according to cited paper.
However, in VSX manual other description of subtype is noted: “They are cataclysmic binary systems with a hot (35,000-65,000 K) and luminous white dwarf that occasionally undergo fadings of more than 1 magnitude (up to several magnitudes) due to a low rate of mass transfer. These fadings might last from days to years.” It is exactly corresponds to observed short fadings of ASAS J071404+7004.3.
