| dc.description | The galaxy cluster RXJ 0152.7-1357 is emitting X-rays at the high rate of 148 counts $ks^{-1}$. It would be one of the most luminous X-ray clusters known if it is at its redshift distance of z = .8325. It is conspicuously elongated, however, toward the bright, X-ray active galaxy NGC 720 about 14 arcmin away. At the same distance on the other side of NGC 720, and almost perfectly aligned, is an X-ray BSO of 5.8 cts/ks. It is reported here that the redshift of this quasar is z = .8312. | |
