Historical Identification:
IC 1165 (= PGC 56769 + PGC 56768)
Discovered (Aug 1, 1891) by Stephane Javelle (366)

PGC 56768 = A 15th-magnitude lenticular galaxy (type E/S0 pec) at RA 16 02 08.6, Dec +15 41 34

IC 1166 (= PGC 56771 + PGC 1771884)
Discovered (Jul 28, 1892) by Stephane Javelle (367)
A pair of galaxies in Corona Borealis
PGC 56771 = A 15th-magnitude spiral galaxy (type S) at RA 16 02 08.9, Dec +26 19 30
PGC 1771884 = A 15th-magnitude spiral galaxy (type S) at RA 16 02 09.0, Dec +26 19 45
(NED lists PGC 56771 as IC 1166 NED02, and PGC 1771884 as IC 1166 NED01; a search based on their PGC listings will fail.) The galaxies appear distorted by their proximity, so they are probably a physical pair, and at the same distance. The recessional velocities are 22024 km/sec for PGC 56771, and 21705 for PGC 1771884. Using their average recessional velocity of 21865 km/sec, a straightforward calculation would put the pair at a distance of 1020 million light years; but for objects at such distances, it is necessary to take the expansion of the Universe during the time it took their light to reach us into account. Doing that indicates that IC 1166 was about 935 hundred million light years away when the light by which we see it left it, about 970 million years ago (the difference between the two numbers is caused by the expansion of the intervening space during that time). Given that and its apparent size of 0.6 by 0.6 arcmin, PGC 1771884 is about 160 thousand light years across, and PGC 56771's apparent size of 0.4 by 0.2 corresponds to about 110 thousand light years' size.

IC 1170 (not = NGC 6040)
(= PGC 56955 = part of CGCG 108-101)
Discovered (Jun 27, 1892) by Stephane Javelle (370)
A magnitude 14.9 lenticular galaxy (type E/SB0) in Hercules (RA 16 04 31.6, Dec +17 43 17)
Historical Identification: Per Dreyer, IC 1170 (Javelle #370, 1860 RA 15 58 13, NPD 71 53.2) is "very faint, very small, very suddenly faint nucleus, (NGC) 6041 following (to the east)." The position precesses to RA 16 04 30.7, Dec +17 43 39, less than 0.5 arcmin northwest of the galaxy listed above, the description fits and there is nothing nearby that could possibly fit the position and description, so the identification is certain. However, despite that, IC 1170 is sometimes misidentified as NGC 6040, hence the warning about that mistake in the title of this entry.
Note About CGCG 108-101: Despite the fact that the CGCG catalog should not have such errors, CGCG 108-101 includes some of the galaxies to the east of IC 1170, hence "part of" in the title for this entry. (Still, that's not nearly as bad an error as the inconceivable misidentification of IC 1170 as NGC 6040!)

Discovered (Jun 3, 1888) by Lewis Swift (VII-71) (and later listed as IC 1179)
A pair of colliding spiral galaxies in Hercules
NGC 6050A = PGC 57058 = a 15th-magnitude spiral (type SA(s)c) at RA 16 05 23.5, Dec +17 45 26
NGC 6050B = PGC 57053 = a 15th-magnitude spiral (type SB(rs)cd) at RA 16 05 22.3, Dec +17 45 16
NGC 6050 (which see for images and physical data is a colliding pair of spiral galaxies known as Arp 272. Per Corwin, even with a 30-inch telescope visual observations do not show any hint of the double, so Swift's two observations cannot refer to the two galaxies, and must be duplicate observations of their combined image (an all too common occurrence for Swift, and not that uncommon for other observers, as well). Steinicke and NED list NGC 6050 and IC 1179 as the same object; but many references list NGC 6050A as NGC 6050, and NGC 6050B as IC 1179 (for instance, LEDA and Wikisky use the incorrect labels). Most significantly, there is a HubbleSite news release of the most spectacular image currently available for the pair which uses the incorrect names, so the error will undoubtedly be propagated across the Internet for the foreseeable future.
