Discovered on February 23, 1752 by Abbe Nicholas Louis de la Caille.
Sweep 449 (May 5, 1834)
RA 13h 27m 27.9s, NPD 119d 0m 16s (1830.0)
v B; v L; s b M to a centre = a star of 9 m, diam 8", of a resolvable
character like a Glob. Cl., surrounded by an immensely L, extremely dilute
almost equable light 7' or 8' diam, somewhat oval, and passing with an
excessive suddenness into the central light.
Very bright; very large; suddenly brighter toward the middle to a centre
resembling a star of 9 m, diameter 8", of a resolvable character like a
globular cluster, surrounded by an immensely large, extremely dilute almost
equable light 7' or 8' diam, somewhat oval, and passing with an excessive
suddenness into the central light.
Sweep 450 (May 6, 1834)
RA 13h 27m 28.5s, NPD 119d 0m 20s (1830.0)
F; v L; E; v s v m b M to a sharp nucleus (ill seen, owing to clouds).
Faint; very large; elongated; very suddenly very much brighter toward the
middle to a sharp nucleus (ill seen, owing to clouds).
Sweep 564 (March 30, 1835)
RA 13h 27m 30.1s, NPD 119d 0m 8s (1830.0)
v L; v B; m E; v s v m b M to a nucleus; diam in RA = 17.5 sec = 3' 49" in
arc; a small * involved; pos with nucl 80deg +/- by a rough diagram made at
that time.
Very large; very bright; much elongated; very suddenly very much bbrighter
toward the middle to a nucleus; diameter in RA = 17.5 sec = 3' 49" in arc;
a small [faint] star involved; position [angle] with nucleus 80deg +/- by a
rough diagram made at that time.
