We report additional photometry of the recent M31 nova, M31N 2024-07c (PNV J00425185+4115512 = AT 2024qui), which extend the observations published in ATel #16749.
The following magnitudes were obtained using the 0.65-m telescope at Ondrejov (D65), the 0.8-m telescope at Zdanice (D80), and the 0.84-m telescope of the San Pedro Màrtir National Astronomical Observatory (S84):

For convenience, the table also includes the four measurements previously reported in ATel #16749.
As with all extragalactic novae, follow-up spectroscopic and photometric observations to confirm the nova's nature and determine its spectroscopic class and rate of decline (speed class) are encouraged.
