Why did we all get it
wrong?
Just before OJ287 disappeared at conjunction in 1994 it was brightening rapidly.
It was much fainter again in September.
Maybe the real outburst happened while OJ287 was invisible?
If the wrong date was used in the calculations for the 1994 outburst, the model and its predictions will be wrong.
