A 15.7-min periodicity in OJ287
Description
The authors report here the detection of a 15.7-min periodic flux variation in BL Lac-type object OJ287 in April 1981 at 37 GHz. The source has been subsequently monitored for 265 h at 22 and 37 GHz, as well as in optical photometry, and the same period has been seen in simultaneous observations. The peak-peak amplitude of the variation is 1-10% of the total intensity. Other periods may also exist. (author)
