TITLE: GCN CIRCULAR NUMBER: 35245 SUBJECT: Optical transient in the field of Messier 31, likely a new blazar: back to bright state DATE: 23/12/01 12:07:03 GMT FROM: Gianluca Masi at Virtual Telescope Project gianluca@bellatrixobservatory.org
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: https://www.virtualtelescope.eu/2023/08/16/discovery-of-variability-of-the-o...
Multi-wavelength observations are strongly encouraged.
