  We are carrying out the densest and longest multiyear, multiwavelength
monitoring project of OJ 287 ever done. The project MOMO (Multiwavelength
Observations and Modelling of OJ 287) covers wavelengths from the radio to the
high-energy regime. A few selected observations are simultaneous with those of
the Event Horizon Telescope (EHT). MOMO aims at understanding disk-jet physics
and at testing predictions of the binary black hole scenario of OJ 287. Here,
we present a discussion of extreme outburst and minima states in context, and
then focus on the recent flux and spectral evolution between 2021 and May 2022,
including an ongoing bright radio flare. Further, we show that there is no
evidence for precursor flare activity in our optical-UV-X-ray light curves that
would be associated with any secondary supermassive black hole (SMBH) disk
impact and that was predicted to start as thermal flare on 2021 December 23.
