Scientific paper

The system PHL 1222 = UM 144 = QSO 0151 +048, which is composed of a close pair of quasars with redshift equal to 1.91, is studied. The distance between the quasar image and its brightest companion is 3.3 arcsec. The characteristics of PHL 1222 that imply it is an interacting quasar pair are discussed. The total mass of the system is estimated as 1. 7 x 10 to the 11th solar masses.
