We report that the new blazar candidate in the field of Messier 31 (NGC 224) reported by G. Masi in GCN 34819 is again on bright state, found at R=17.9 on 29.72 Nov. 2023.
The optical source, which discovery is described in the GCN circular mentioned above, has been brighter than R=19.0 since at least 10 Aug. 2023, showing an almost 1.5 mag. large amplitude in its light curve.
Extensive, R-band photometry since 10 Aug. 2023 is available at the following web address:

Multi-wavelength observations are strongly encouraged.
