Mean supercycle 90 days with four or five normal outbursts between the superoutbursts. ASAS-SN magnitudes are contaminated by SDSS J200647.32+415823.9 (V= 16.0; sep. 9.2"), SDSS J200647.11+415826.0 (V= 16.4; sep. 9.4"), SDSS J200648.17+415820.3 (V= 17.1; sep. 11.7") and partially contaminated by SDSS J200648.09+415847.5 (V= 15.8; sep. 16.5").
