Abstract

A quasar search in the region of the active galaxy NGC 1097 yielded 31 quasars in 1984. After completion of the 2dF survey in 2004 the number of catalogued quasars just within 1 degree of the galaxy increased to 142. About 38 $\pm$ 10 of these are in excess of average background values. The evidence in 1984 is confirmed here by an increasing density of quasars as one approaches NGC 1097. Quasars within 1 degree differ from the background by being significantly brighter. There also appear two elliptical rings or arcs of quasars at r $\sim$ 20'and 40'.
