7. NGC 6027 Sextet
This group of galaxies in Serpens was discovered by Seyfert (1951). Three
members are spirals, the two brightest are S0 or Sa, and one is a peculiar
diffuse irregular galaxy. The velocities of the two brightest members were
measured by both Humason and Mayall (Humason et al. 1956); they are well
determined and are +4568 and +4160 km/sec. Magnitudes were measured by Seyfert;
they range from 14.7 to 16.9. No analysis can be carried out until more measures
of velocity are available. We note that the difference of about 400 km/sec
between the two measures is of the same order as the extreme range of velocities
measured in VV 116. The distance of the system is about 58X 10^6^ pc, and the
largest dimension of the group is only about 27 kpc (not corrected for
projection) so that the galaxies are very small.
