According to some professional articles, on July 31, 2019, a maximum of light would occur in the optical as its Gamma flash. As observed above, it did not occur, at least in Gamma rays because in the optical it coincides when it was not observable when it was close to the Sun.
I understand that if an external object, such as the supposed binary supermassive black hole, were to enter the vicinity of the central supermassive black hole OJ 287, it would have caused such instability that it would no longer be predictable. As seen at the maximum 1280 days, at the minimum 1425 days, at the maximum 1530 days and at the minimum 1640 days since the main explosion, it is clear that OJ 287 remains predictable.
In fact, I presented the prediction that an explosion would occur at 1280 days, both to the scientific community and at the Huesca Congress (Spain), before amateur and professional astronomers, both the maximum in the optical and the Gamma flash, and so it happened. I had an error of less than 5 days, which is my error range.
In summary, OJ 287 is a normal blazar and is not a binary system.
