ASASSN-V J205543.90+240033.5 (AR Sco-like object): true period
After an analysis of the ZTF data, I reached a conclusion that the true period is 0.523490(1) d. All the data can be well expressed by this period and the profile is sinusoidal (reflection type). The 10.803 d period I reported appears to be its alias. The initially reported 0.2-d period was caused by the incomplete phase coverage.
Now this object looks even more similar to AR Sco (Porb=0.14853528 d, spin=1.95 min). I will publish a corrected report shortly.
Special thanks to Elena Pavlenko for pointing out the likely error in the period.
