NGC 5527 is probably the object called "NGC 5524" by virtually everybody.
Found by LdR on 19 April 1855, it has just the one observation recorded under
LdR's entry for NGC 5529.  That observation reads, "[NGC 5529], long narrow
ray with a S, R, vF neb sf; another vF about 15' np [5529]; and another eeF
about 6' p and 1' n of this last."  Dreyer adds the note, "The positions
given in the G.C. for 2 R. novae, [5524] and [5527], are not in accordance 
with this."

In the observation, it's clear that there are four nebulae in the field.  One
of these, the "S, R, vF neb sf" is neither in GC nor NGC (it is one of 
several nebulae known to Dreyer that he did not include in NGC).  The other 
three nebulae, N5524, N5527, and N5529 are arranged along a curve according to 
LdR's description.  It is also clear that the new objects can have only
approximate positions as no micrometric positions for them were measured at
Birr Castle.

An additional problem concerns the adopted positions and descriptions.  The
positions are by JH for GC and, as Dreyer noted, do not correspond with the
description given by LdR.  Dreyer switched the positions for NGC, but still
got LdR's descriptions of brightness reversed -- the faintest object is
clearly the western most of the objects, i.e. NGC 5524.

Given all this, it is reasonable to suppose that the brightest object 
northwest of NGC 5529 is NGC 5527, and that a still fainter object is west-
northwest of it.  This makes N5527 = CGCG 191-067 (it is 17.2 arcmin from
N5529), but leaves the position for NGC 5524 vacant.  The object was taken to
be a star by Carlson, and was noted in MCG as "Not found."  There is a very
faint galaxy in the right direction from N5527 that LdR might have seen, but
it is almost 13 arcmin away, not 6+ arcmin as in the observation.  There is
also a somewhat brighter triple star on to the northwest of N5527 (14 11 42.2,
+36 43 48; B1950.0, mean of the three DSS positions), but it is 9.5 arcmin 
from the galaxy, and is probably too bright to be called "eeF."  The stars
are also pretty well separated:  the northern star is 30 arcsec away from the
southern.

The final possibility, the one I've adopted, is the double star 7.9 arcmin 
west-southwest of N5527.  This is a reasonable choice if LdR's description 
reads "... another eeF about 6' p and 1' s ...."  The second star of this 
pair is much fainter than the brighter, but may have added just a hint of 
nebulosity to the object.  While this identity is a (reasonable) guess, it is 
still the best of the available options. - Dr. Harold G. Corwin, Jr.
