Sep. 2018 superoutburst in ZTF data has started with a precursor similar to
those in V1504 Cyg described by Y. Osaki and T. Kato, 2013 in PASJ, Vol.
65, p. 50.

Orbital period is unknown. Time-resolved photometry is encouraged. If the
star dims by a magnitude, please don't drop it! It may be a short dimming
between the precursor and superoutburst, as in 2018.
