Shafter in ATel #7116 confirms that the PNV is positionally coincident with M31N 2006-11c. The derived absolute magnitude of −8, together with its classification as a very fast nova with (t_2 = 1.8) days, is also consistent with the observed properties. These findings lead us to conclude that the transient AT 2026wvv represents a recurrent eruption occurring 10.5 years after the previous event reported in ATel #7116. N

Unfiltered CCD camera). No stellar source was visible at the position of the transient in our past images including reference image dated 2026/07/30 22:53:48. The PNV is located 0.68" from the recurrent nova M31N 2006-11c. 2026TNSTR3123....1C N
