IC 2006 (= PGC 14077)
Discovered (Oct 3, 1897) by
Lewis Swift (XI-63)
A magnitude 11.3 lenticular galaxy (type E/S0??) in Eridanus (RA 03 54 28.3, Dec -35 58 02)
Apparent size 1.9 by 1.6 arcmin?

IC 2007 (=
IC 2008 = PGC 14106 = PGC 14110)
Discovered (Oct 5, 1896) by Lewis Swift (and later listed as IC 2008)
"Rediscovered" (Dec 26, 1897) by Lewis Swift (XI-64) (and later listed as IC 2007)
A magnitude 13.0 spiral galaxy (type SB(rs)c) in Eridanus (RA 03 55 22.6, Dec -28 09 32)
Swift misrecorded the position of this galaxy both times he observed it, hence its inclusion in the IC with two different numbers. However, per Corwin, his descriptions of the two observations make it clear that they refer to the same object. Based on a recessional velocity of 1515 km/sec, the galaxy is about 70 million light years away. Given that and its apparent size of 1.35 by 0.7 arcmin, it is about 30 thousand light years across.

A magnitude 14.5 lenticular galaxy (type S0/a?) in Taurus (RA 04 01 53.7, Dec +05 38 21)
Apparent size about 0.8 by 0.5 arcmin. Apparently interacting with PGC 200219, but Javelle's description gives no indication that he was aware of the existence of the fainter galaxy, so it is not considered part of the IC entry.

IC 2026 (=
NGC 1509 = PGC 14393)
Discovered (Oct 22, 1886) by Lewis Swift (and later listed as NGC 1509)
Also observed (1886) by Ormond Stone (and later listed as NGC 1509)
Discovered (Dec 16, 1897) by Guillaume Bigourdan (and later listed as IC 2026)
A magnitude 13.7 spiral galaxy (type Sa?) in Eridanus (RA 04 03 55.0, Dec -11 10 46)
Historical Identification:
Physical Information: Given the duplicate entry, see NGC 1509 for anything else.

PGC 14389
Not an IC object but listed here because sometimes misidentified as
IC 2026
A magnitude 15(?) lenticular galaxy (type S0/a?) in Eridanus (RA 04 03 50.5, Dec -11 10 52)
Historical Identification: Too faint to have been seen by any of the discoverers of NGC 1509 = IC 2026, but sometimes misidentified (e.g., by LEDA) as IC 2026.
Physical Information: Based on a recessional velocity of 8875 km/sec, PGC 14389 is about 410 million light years away. (Need to discuss relativistic correction to these numbers.) Given that and its apparent size of 0.5 by 0.2 arcmin, it is about 60 thousand light years across. It may be associated with the galaxy that it is misidentified with (IC 2026 = NGC 1509, which see for images), as the difference in their recessional velocities is within the range of normal peculiar (non-Hubble expansion) velocities; but it is more likely that they are separated by millions of light years.

Discovered (Jan 18, 1898) by

Perhaps discovered (Dec 31, 1885) by Ormond Stone (and later listed as NGC 1538)
Discovered (Jan 20, 1900) by Herbert Howe (14) (and later listed as IC 2045)
A magnitude 14.4 lenticular galaxy (type E/S0) in Eridanus (RA 04 14 36.0, Dec -13 10 30)
(See NGC 1538 for a discussion of the slight possibility that this is also Stone's observation.) Based on a recessional velocity of 9100 km/sec, IC 2045 is about 425 million light years away. Given that and its apparent size of 0.9 by 0.7 arcmin, it is about 110 thousand light years across.

Discovered (Jan 20, 1900) by Herbert Howe (15) (and later listed as IC 2047)
A magnitude 15.1 spiral galaxy (type S?) in Eridanus (RA 04 14 56.0, Dec -13 11 29)
(See NGC 1538 for a discussion of the possibility that this is also Stone's observation.) Based on a recessional velocity of 8055 km/sec, IC 2047 is about 375 million light years away. Given that and its apparent size of 0.95 by 0.45 arcmin, it is about 100 thousand light years across. (Almost nothing is known about PGC 941469, so whether it has any relationship to IC 2047 save being in the same direction is mere speculation.)
