1.7 GHz VLBA image from 2005.82 of HST-1. The Gaussian fit to the component ejected during the 2005 flare, component c, is very elongated along a direction that is close to the local upstream jet direction in Fig. 1. The single Gaussian fit is an ellipse, 9.2 mas × 1.3 mas (unresolved) at PA = −51°. Components a and b are off to the right and are too faint to be revealed by this contour map. The Gaussian beam FWHM in blue provides a scale for the image.
