. The faint filaments of the giant supernova remnant known as the Cygnus Loop are visible in this image obtained with the wide-field view of the Mosaic camera on the WIYN 0.9-meter telescope. Because of its immense size, it contains several individually named objects, including NGC 6992 and IC 1340 on the left side as well as NGC 6960 and Pickering's Triangle on the right. // T. A.

. Comment on J0405+3803 . Our image contains a feature of 25 mJy at 14 mas E-NE from the brightest component. It is not visible in the Caltech-Jodrell (CJ) survey image at 5 GHz (Xu et al. 1995) obtained about 6 years earlier. The 1.6 GHz CJ image (Polatidis et al. 1995) does show an extended feature close to the position in question, but somewhat displaced toward west. VLBApls home page . Last modified: 16 Oct 2000
