OJ287 in 2025

About this image

My 33rd consecutive year of monitoring this Binary Black Hole. 2025 started with a fade to a near historical low state (17.04V) in February, followed by a jet event (flare) two magnitudes brighter in April. OJ was picked up after Solar Conjunction on September 10, and increased in brightness to magnitude 14.5V by November, followed by a steady slow decline to the end of the year.
