Following the reports of unusually high state across the spectrum (ATel #17873, ATel #17874 and the references therein) of the changing-look blazar B2 1420+326 (OQ 334, z=0.68) we continued monitoring this object with the 60-cm Belogradchik telescope, Bulgaria. Photometric and polarimetric measurements were performed during the nights of July 9th and 10th. The preliminary results are listed below:

JD R-mag (err) P (err) [%] EVPA (err) [deg]
2461231.37 12.42 (0.03) 12 (1) 46 (2)
2461232.34 12.52 (0.03) 8 (1) 32 (2)

To the best of our knowledge, brighter R-band magnitudes have never been reported before for this object, especially what concerns the night of July 9th. Further multiwavelength observations are encouraged. This research was partially supported by the Bulgarian National Science Fund of the Ministry of Education and Science under grants KP-06-H78/5 (2023), and KP-06-H88/4 (2024).
