AF Sco and AC Sco


(from vsnet-chat 147)

AC Sco also a non-cv? It's a close neighbour to AF Sco. Is it not strange that often similar peculiar stars or stars with similar records are close neighbours (in the sky), and that novae seem to occur in certain regions during brief periods and occur in other regions during later periods. I don't have examples of it here, but I remember this impression re-occuring several times. In how far is this coincidence? Or is this a matter of mistaken impressions?
