Lens System Summary
B0850+054 is a two-image system with a separation of ~0.68 arcsec. VLBA observations at 5GHz show that the stronger (A) image is tangentially stretched over ~20 mas and has at least 5 sub-components. The weaker image is radially stretched but the resolution is not high enough to show the individual sub-components. UKIRT observations in K band show both the lens and the strongest lensed image.
