by Taichi Kato 15 Apr '23

15 Apr '23

TCP J12363806+0213281: possible early superhumps Kiyota-san, Sano-san and Itoh-san have reported observations. The object appears to show early superhumps with a period of 0.0547(1) d with an amplitude of 0.07 mag. The weather condition in Japan, however, is not ideal and further observations are need to confirm the period.
