Description
We report on optical spectroscopy of Swift J1933.9+3258 (=1RXS
J193347.6+325422). This X-ray source has recently been classified as a
likely radio-quiet AGN on the basis of its broad-band (radio, optical,
UV, X-ray) properties (Grupe et al. 2006, ATel #859). In order to
confirm its nature, a single 7-min spectrum of the optical counterpart
was acquired on June 20 2006 08:53 UT with the 1.5m Tillinghast
telescope on Mt.Hopkins using its FAST spectrograph.
