TCP J23291172+4127354: new eclipsing WZ Sge-type dwarf nova
TCP J23291172+4127354 was discovered by Y. Nakamura on 2024-12-04.5385 at 14.1 mag (unfiltered). The counterpart in Pan-STARRS1 is g= 21.6 mag (objID= 157753522991272187), hence the outburst amplitude is ~7.5 mag. http://www.cbat.eps.harvard.edu/unconf/followups/J23291172+4127354.html https://www.aavso.org/vsx/index.php?view=detail.top&oid=2390566
Time-resolved observations reported by Itoh-san on the 5th and 6th Dec show double-peaked profiles and superposed eclipses. Its period and amplitude are obtained as 0.05693(2) d and ~0.5 mag (0.3 mag hump + 0.3 mag eclipse).
Thus TCP J23291172+4127354 is a new (and yet another!) eclipsing WZ Sge-type dwarf nova. This would be another nice target for time-resolved photometries.
