Sequence of 15.4 GHz VLBA images showing structural changes in the quasar 2023+335 during a 10.8 yr period. The first two images are non-MOJAVE image from the VLBA archive. The most dramatic parsec-scale variations occurred between 2008.9 and 2009.4 marked by a red box. For each epoch we present two images. The first image is a naturally weighted total intensity map with linear fractional polarization overlaid according to the color wedge. The second image includes the lowest positive total intensity contour from the first image, and linearly polarized intensity contours together with electric polarization vector directions. The crossed ellipse in the lower left represents the FWHM of the restoring beam of 0.96 × 0.56 mas at , which is the median for all restoring beams at the 16 epochs. One milliarcsecond corresponds to about 3.5 pc at the source redshift of z = 0.22. The image parameters are listed in Table 1.
