Re: ASASSN-22dl: new WZ Sge-type dwarf nova with large-amplitude early superhumps Using the ZTF data, I obtained Min(BJD) = 2458713.27415(12) + 0.05561039(3) d This is a deeply eclipsing WZ Sge-type object whose eclipse minima were below the detection limit of the ZTF observations. Orbital humps before the eclipses were also apparent, suggesting that the mass-transfer rate is not very low. The period of early superhumps (but still from a short baseline) is shorter than the orbital period by 0.13%, typical for a WZ Sge star. Tampo-san and Sebastian, please be careful about in drawing the conclusion. The ZTF data also have one-day aliases.
