. Comment on J2206-1835 . Resolved: the source is extended, and has been detected only on the short Australian baselines at 2.3 GHz by Preston et al. (1989). Moellenbrock et al. (1996) did not detect the source in the 22 GHz VLBI survey. The correlated flux density is 1.2 Jy on the shortest VLBA baseline (see Figure 3). VLBApls home page . Last modified: 16 Oct 2000
