Corwin's Notes
=====
NGC 313 is a triple star (the third star is very close to the northern of the
brighter two) about an arcminute north west of NGC 315. Lord Rosse observed
the group (NGC 311 and NGC 318 are the other two bona fide galaxies in it) on
six different nights, and saw the triple as nebulous on all but one night when
he noted it as a double star (his sketch was apparently made on that night as
it shows N313 as a double star). His micrometric offsets from N315 on three
nights point exactly to the triple.
The southern star is just bright enough that it was picked up in GSC. The
position I've adopted is midway between this and the image of the northern
two stars.
