- Аннотация: The discovery of the outburst in the nucleus of NGC3822 and the Changing-Look AGN classification were reported in ATel #15280 (see details there). Our optical UBV photometry shows that the activity of NGC 3822 is going on and that the Changing-Look nucleus is now brightening significantly.We have obtained UBV CCD photometry with the 0.6-m telescope of the SAI Caucasus Mountain Observatory for 9 dates during 21 March - 24 April 2022 . The used aperture is 10 arcsec and the U magnitudes are reduced to the U system of the UVOT Swift (using observations which were done on the same dates). From our photometry the brightness of the NGC 3822 changed from U=15.15+/-0.02 (21th March) to U=14.93 +/- 0.02 (21th April) and then moved a little bit down to U=14.97+/-0.02 (24th April).This work has been supported in part by M. V. Lomonosov Moscow State University Development Program.
