Here's the discovery image I took remotely from the Burke-Gaffney Observatory @BGO.observatory.social.ap.brid.gy . Follow-up photometric and spectroscopic observations of this most recent eruption of M31N 2008-12a are strongly encouraged.🔭

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.

Yesterday, I remote observed the transient TCP J06330104+0303350= Gaia DR3 3130088774241620608 using the Burke-Gaffney Observatory (BGO @BGO.observatory.social.ap.brid.gy ). Based on my observations, it has been confirmed as an eclipsing WZ Sge-type dwarf nova with an orbital period of 0.05786 days🔭

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.🔭

According to the prediction, the recurrent nova T Corona Borealis (T CrB) will outburst in the near future, and global monitoring is very necessary. We sincerely invite amateur astronomers around the world to join our initiative on monitoring T CrB, please read the initiative below.🔭 🧪

🔭🧪 We believe it is very similar to KH 15D, which has been called as the "Rosetta Stone" for understanding planetary formation, the brightness variations may be formed by a circumbinary disk obscuring the centre binary star. This variable star has been indexed by VSX: www.aavso.org/vsx/index.ph...

Our amateur team has discovered an interesting eclipsing variable star near SH 2-241 nebula from ZTF archive data. It has a period about 830 days, more than 40% in occultation, with a bright peak at the centre of the occultation. 🔭🧪

Thanks for sharing, great article! I have been following T CrB for a long time and hope it will outburst soon. By the way, I found a historical image of its 1946 outburst in the Harvard Observatory's Plates database (starglass.cfa.harvard.edu/plate/ac39501), see ALT for details. 🔭

In an urban area with serious light pollution, the Seestar S50 was used to monitor the upcoming outburst of the recurrent nova T CrB. Because Seestar S50 doesn't have this object in its database, I chose GOTO to the nearby galaxy IC 4587, which places T CrB almost perfectly at the center. 🔭
