A0642 radio identifications

A0642 08 19 05.7 +30 02 34  0.2063e
# RS1 is HT radio galaxy of cluster.
# Faint compact detail in the tail of this radio source
# coincides in position with other cluster galaxy
# APM J2000 08 19 10.31  +30 03 37.5 mR = 18.96
# (i.e. possible cluster radio galaxy too).
# Possibly, NVSS RS2 is in cluster (need the radio structure).
# Unusual (3C315 type) radio source (RS7) is in other cluster, probably.
