Abstract (from CDS):

VLBI maps of the high-redshift quasar 1338+381 (z=3.1) have been made at five epochs between September 1992 and May 1994. They reveal structure with two well defined components separated by 3.6 milliarcseconds and suggest at one epoch a third weaker component in between. We have significant evidence that the two main components are stationary over the 1.7 year period of observations and might result from a bent jet structure, as in 4C 39.25. We propose a scenario in which the weaker third component moves between the two stationnary components at the high apparent velocity of 27±17h–1c. We discuss briefly the location of this new compact F double sou rce in the µ-z diagram.
