VLBI Detection and Astrometry for AT2018cow
Abstract
We obtained 22-GHz VLBI observations of AT2018cow with the NRAO VLBA and Effelsberg telescopes. The midpoint of the observations was 2018 July 8.1 UT. We detect the source with a total flux density of 5 mJy. We obtain a preliminary position of RA = 16h 16m 00.2242s, dec = 22d 16' 04.890 & quot; with an estimated uncertainty of 60 micro-arcsec.
