Re:ABELL 2069
A 2069. The diffuse emission is located to the SE with respect to the
cluster center at a distance of ~6Mpc, therefore its classification as a
cluster relic is uncertain. The image of this region retrieved from the
FIRST survey shows a faint point-like source coincident with the
southernmost peak, while the whole structure is resolved out.

Re:ABELL 2069
This cluster is particularly extended and the X-ray centroid lies
between two bright galaxies; one the central dominant galaxy in A2069
(galaxy a). Our spectrum of the second bright galaxy at RA 15 24 22.7
and Dec 29 57 25 (J2000) shows it to be a foreground active galaxy at a
redshift of 0.076. This galaxy may be a weak contributor to the total
X-ray emission from the cluster, and we note that its redshift
suggests that it may be a outlying member of the nearby cluster
A2061. Also along our slit position for galaxy a are two other
cluster galaxies (b and c) 26 arcsec to the NW of galaxy a, and
separated from each other by only 4.1 arcsec (11kpc). This cluster
is an EMSS cluster.

Re:MS 1522.0+3003
An optical and X-ray study of Abell 2069 has been published in Gioia et
al. (1982), where an X-ray iso-contour map is also presented. The cluster
shows multiple condensations in both the X-ray emission and the galaxy
surface density and thus the system as a whole does not appear relaxed.
The close correspondence between the gas and the galaxy distributions
seems to indicate that the galaxies in this system do map the mass
distribution. A possible blue arc was discovered by Donahue, Stocke &
Gioia (1992) North of the two central brightest galaxies. However, this
cluster is at too low redshift to enter our 41 cluster sample.
