1890 年至 1991 年间 OJ 287 上所有可用的光学 B 波段数据均已汇编。使用这些数据,发现 OJ 287 爆发的周期为 11.6 ± 0.5 年。该值与 Sillanpaa 等人先前发现的爆发之间的 11.65 年周期和最小值之间的 11.05 年周期非常一致。 (1988, ApJ, 325),使用 V 波段数据。根据这个时期我们可以预测下一次爆发应该在 1994 年 8 月左右达到最大值
All the available optical B band data on OJ 287, between 1890 and 1991, have been compiled. Using this data, a period of 11.6 ± 0.5 yr was found for the outbursts in OJ 287. This value is in good agreement with the period of 11.65 yr between outbursts and 11.05 yr between minima found previously by Sillanpaa et al. (1988, ApJ, 325), using V-band data. Based on this period we can predict that the next outburst should be at its maximum around August 1994
