H-alpha monitoring of OJ 287 in 2005-08

We present the results of H-alpha monitoring of the BL Lac object OJ 287 with the VLT during seven epochs in 2005-08. We were able to detect five previously undetected narrow emission lines, 6548,6583[NII], 6563H-alpha$ and 6716,6731[SII] during at least one of the epochs and a broad H-alpha feature...
