IC 2872 is the brightest part of a large (18 arcmin by 16 arcmin) diffuse
nebula. The IC object itself has two or three bright lobes, perhaps defined
(as in the Trifid Nebula) by dust lanes. The positions I give in the table
are eyeball means for the two and three brightest lobes, while that that
Andris measured for ESO-B perhaps includes the apparent cluster that the
nebula envelopes.

Frost's description "bM, neb. ext. 2' in R.A. and 5'.0 in Dec" matches the two
western lobes almost perfectly. His position (given only a tenth of a minute
of time and an arcminute in Dec) corresponds to a star a little east of the
midpoint of these two brighter lobes, but is still within his usual error.

Most of the fainter part of the nebula extends on to the northeast from the IC
object itself.
