Abstract:
 The binary black hole model was proposed to a well known blazar OJ 287
by Sillanpaa et al. (1988) based on the periodic optical outbursts with a
cycle of about 12 years. The authors also predicted the next outburst in
1994 succesfully. The next outburst based on this model should occur  at
the end of September 2006 so during this conference we already know
if also this prediction was succesful and we can really confirm the binary model.
Otherwise we have to find a new model..
