ASASSN-V J205543.90+240033.5: combination of three periods

Josch Hambsch and Tonny Vanmunster have reported observations. See https://arxiv.org/abs/2108.09060 http://vsolj.cetus-net.org/vsoljno80.pdf "ASASSN-V J205543.90+240033.5: another white dwarf pulsar?"

Their observations indicate that the global variation is a combination of the longer period 10.803 d and a shorter period 0.203424(1) d (determined from the ZTF data). These variations create the dispersion in figure 2 of the above paper.

Their data also confirmed the short period of 0.0067876(7) d (amplitude 0.07 mag).

This must be a very interesting CV-like object and further observations (including spectroscopy) are requested.
