When compiling our list of all known eruptions of M31N 1926-07c in ATel #15608, we failed to note that M31N 2020-01b was apparently also a recurrence of M31N 1926-07c. Thus, M31N 2022-09a is actually the fifth reported eruption of this recurrent nova.
The interval between the past two recorded eruptions suggests that the recurrence time of M31N 1926-07c is of order 2.7 years (or possibly an integer fraction of that) making it currently the second shortest nova recurrence time known after the ~1 year interval for M31N 2008-12a.
