EF Eri: dips Observations by Kiyota-san and Itoh-san clearly shows short-duration dips such as at 2022 Dec. 25.618 (UT). These dips were not seen in every orbit but were present almost on every night. The durations were 2-3 min and were 0.8-mag deep. Ingress was slower and egress was sometimes sudden (within 30s).
