[vsnet-newvar 10078] Please also observe ASASSN-22ak (southern object)
by Taichi Kato 12 May '23

12 May '23

Please also observe ASASSN-22ak (southern object) Josch Hambsch has been reporting observations. The data, however, were not sampled sufficiently and it is difficult to find a period. There is a suggestion of a period of 0.0453 d (consistent with the rapid fading observed in the 2022 superoutburst?). This object underwent the first-known outburst in 2022 Jan. (long after a dormant period?) and repeated unusual outbursts since then. The current outburst is the fourth one. Although there may be another outburst later in this year, there may be no guarantee since the present activity is a transiently enhanced one (as in V3101 Cyg). So I recommend to observe every outburst as closely as possible.

[vsnet-newvar 10077] Gaia DR3 2893005857946801152 = ASASSN-23dr: most likely WZ Sge star
by Taichi Kato 12 May '23

12 May '23

Gaia DR3 2893005857946801152 = ASASSN-23dr: most likely WZ Sge star Berto Monard and Josch Hambsch have reported observations. Using Monard's data, there appears to be a period of 0.05452(5) d with a double-peaked profile. The result, however, is preliminary since the amplitude was small (0.03 mag) and observations are still limited. I used the name Gaia DR3 2893005857946801152 since this object was selected as a variable by Gaia (there was probably simply no concept of a dwarf nova in quiescence and was classified as a WD). Please feel free to use ASASSN-23dr since it is much shorter.
