ASASSN-22ak period

Josch Hambsch has reported further observations. Thanks to the recent high-cadence data, the period has been established. The object brightened a bit on May 21 and the period since then has been 0.04292(2) d. Based on this alias selection, the period from the entire data is 0.043032(4) d. The profile still never appeared to be typical superhump-like. It has been fast rising and slower fading, as in early superhumps. The amplitude is 0.04 mag. The observations appear to confirm the classification of the object as being below the period minimum (EI Psc star).
