Figure 1 shows the light curve I measured from the BGO data. Figure 2 shows the phase plot. My photometric data are available from the AAVSO database.

In addition to these two outbursts, I also led the discovery of the 2022 outburst (M31N 2022-03d). Reference: www.astronomerstelegram.org?read=15729

The putative quiescent optical counterpart is so bright that it is clearly visible in images taken by some amateur astronomers.

The putative quiescent optical counterpart is so bright that it is clearly visible in images taken by some amateur astronomers.
All in all, this is a very interesting nova system. A complete model for the system will require a more thorough investigation of the quiescent counterpart, which is currently underway.

In an attempt to characterize the quiescent counterpart, Prof. Shafter et al. obtained a spectrum of the putative quiescent counterpart using the Hobby-Eberly Telescope in Jan. 2023. The spectrum is dominated by a blue giant, which cannot be explained by current models.🔭

The counterpart of the nova is likely associated with a blue 20.5 mag variable star that displays 14.3 d period. At the distance of M31, absolute magnitude of the putative quiescent counterpart is ∼ −4, given its blue, would be unprecedented for known recurrent nova system.🔭

M31N 2017-01e has a recurrence time of ~2.5 yr, which is the second shortest known for any nova. After adding the two outbursts I recently discovered, the nova is known to 6 outbursts, which is the second most in the M31 galaxy. We expect the next eruption occur in Mar. 2027.🔭

I made follow-up observations of this PCCP object remotely using the Burke-Gaffney Observatory (code 851) at Saint Mary's University, and the measurements are on the PCCP. ☄️🔭
