Near-in-time 3 mm and 7 mm VLBI observations of OJ 287 in ~2012.4. Contours: −1, 1, 2, 4, 8, 16, 32, 64% of peak flux density. Beam size and peak flux density are shown in the bottom right corner. The restoring beam ellipse is shown in bottom left corner. The position and size of Gaussian model-fit components is represented as filled blue circles within the map. Labels represent the identification of the VLBI component. Other epochs are shown in Appendix.
