[vsnet-alert 26450] ASASSN-21uy: new SU UMa-type dwarf nova
by Taichi Kato 20 Nov '21

20 Nov '21

ASASSN-21uy: new SU UMa-type dwarf nova Berto Monard has reported observations. Humps with a period of 0.0613(5) and a mean amplitude of 0.09 mag were recorded. Although the profile was doubly humped, the overall feature did not resemble that of early superhumps. The superhumps may be in the growing phase. Further observations are needed to see whether these humps are ordinary superhumps in the growing stage or early superhumps.

[vsnet-alert 26449] TCP J17242302+3258109: Possible appearance of ordinary superhumps

TCP J17242302+3258109: Possible appearance of ordinary superhumps Kiyota-san and Kyoto Univ. Obs. have reported the observation of TCP J17242302+3258109. Time-resolved observation on 19th Nov. at Kyoto Univ. Obs. showed a large amplitude (~0.2 mags) variation, which can be ordinary superhumps. Due to the limited visibility, the baseline was not enough to determine its variation period. Best, Yusuke
