Abstract:

The position of the radio source 3C 17 is derived from 9 occultation events recorded at three observatories. The positional accuracy is about 0.5 second, and a 19th magnitude galaxy is found within 1 second of the radio position. Occultation and interferometric measurements indicate that the source is probably of the corehalo type, with a maximum diameter of 20-30 seconds. The optical spectrum of the galaxy shows emission lines typical of other radio galaxies, thus confirming the identification the redshift is 0.2201. Author
