Corwin's Notes
=====
NGC 5284. This cluster is nearly lost against the rich background of the
Milky Way, so is difficult to identify. JH describes is as a "Cl class VIII.
L, v rich, loosely sc; sts 7.8 ... 16 m; it is an outlier of the milky way,
but very rich and much insulated." His position corresponds to that of the
brightest star in the area, HD 119744; at V = 9.35, it is somewhat fainter
than JH's estimate.
If this is indeed the cluster that JH saw, its center is about 20 seconds of
time east and 4.5 arcminutes north of the star. I think this is the most
likely candidate for JH's object, but we really do need a visual observation
(Steve Gottlieb hasn't yet gotten to this southern object; July 2015).
There is also a Milky Way star cloud, about 30 arcmin by 20 arcmin, centered
about 45 seconds of time following, and four arcminutes north, of JH's
position. It also more or less matches his description, and could be his
object.
Finally, Archinal has this as "... the Milky Way patch, centered on the star
HD 119837 (V = 10.6)." This is a part of the star cloud noted in the previous
paragraph.
