Descripción
The polarization spectrum of OJ287 was obtained during the 1993/94
observing campaign within the OJ-94 International Collaboration. Data
were taken on December 17-18-19/1993, an on Januarty 11-12/1994. Between
both periods of observations, OJ287 showed minor flare activity, where
brightness raised from V=15.75 to V=15.25, and the polarization degree
varied between 0.5% and 8%. On the spectra taken on January 11, we have
also observed large variations in the polarization angle ~ 90(deg) ,
associated with changes of ~ 2% in the polarization degreee. We have
also observed the [OIII]5007 emission line; we investigate its
appearance during change in brightening conditions, and preliminary
results will be presented.
