ASASSN-21ls: dwarf nova below the period gap with strong reflection effect From ZTF data. Porb = 0.0579261(1) d. The orbital profile looks like a detached subdwarf binary. There was indication of primary eclipse (but not sharp, probably due to the accretion disk). Total amplitude 0.58 mag. Too red for this Porb and the secondary may be evolved.
