Bright outburst of the blazar 4C 31.03
Active Dates: Jan. 1, 2023 – Jan. 1, 2023
Abstract:
The blazar 4C 31.03 is undergoing an unprecedentedly bright outburst. Ciprini et al. report that gamma-ray flaring in this Active Galactic Nucleus (AGN) was detected by the Fermi Large Area Telescope (LAT) on 2023 January 1 and 2. Follow-up optical observations by Seiichiro Kiyota show the quasar brighter than ever previously detected. Sebastián Otero provides the compiled historical light curve demonstrating the unusual nature of the current outburst.
Justification:
Follow-up observations in all filters (UBVRI) are recommended until the quasar has returned to its normal behavior. DSLR observations are also welcome. The usual range of 4C 31.03 is V magnitude 15-19.
