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

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
