Scientific paper

J band photometry of OJ 287 has been carried out with a time resolution of 5 s using the 3.8-m UKIRT. Significant variations in brightness of up to one magnitude have been observed. Several distinct outbursts can be identified in the photometric record and rise-times and decay-times as short as 1 min were seen. These observations provide evidence of highly anisotropic and/or relativistic effects in the central source.
