[vsnet-outburst 31222] Gaia DR3 3130088774241620608: confirmation as a WZ Sge-type dwarf nova
Gaia DR3 3130088774241620608: confirmation as a WZ Sge-type dwarf nova
Itoh-san and J. Hambsch have reported the time-resolved observations of Gaia DR3 3130088774241620608 = TCP J06330104+0303350. The light curve shows a large-amplitude double-hump profile and superposed eclipses. Combining with AAVSO observations by J. Zhao, I obtained the early superhump+eclipse period as 0.05786(1) d. The orbital profile amplitude is ~0.5 mag; 0.3 mag early superhump plus 0.3 mag eclipse. Therefore, Gaia DR3 3130088774241620608 is now confirmed as an eclipsing WZ Sge-type.
Time-resolved observations are strongly encouraged! best regards, Yusuke

TCP J06330104+0303350 = Gaia DR3 3130088774241620608
TCP J06330104+0303350 was discovered by T. Kojima on 2024-11-28.76 at 13.9 mag and now brightened to V=13.4 mag according to TOCP reports. http://www.cbat.eps.harvard.edu/unconf/followups/J06330104+0303350.html
This system has already been pointed as a WZ Sge-type cataclysmic variable candidate in Inight et al 2024, named Gaia DR3 3130088774241620608. https://www.aavso.org/vsx/index.php?view=detail.top&oid=2389763 https://ui.adsabs.harvard.edu/abs/2024MNRAS.tmp.2451I/abstract
This outburst is a great opportunity to determine its outburst nature as well as derive its superhump periods. Time-resolved observations are encouraged.
Best regards Yusuke

Gaia DR3 3130088774241620608: appearance of ordinary superhumps
Most recent observations reported by Itoh-san, Vihorlat Observatory, J. Hambsch as well as those reported in AAVSO show single-peaked variation and superposed eclipses. Therefore, Gaia DR3 3130088774241620608 is now in the ordinary superhump phase. Time-resolved observations are still strongly encouraged to study its superhump period evolutions.
Best regards, Yusuke
