IC 200 (= PGC 7967)
Discovered (Dec 1, 1866) by
Truman Safford (71)
A magnitude 12.9 spiral galaxy (type SBbc?) in Triangulum (RA 02 05 26.6, Dec +31 10 32)
Per Dreyer, IC 200 (Safford #71, 1860 RA 01 59 18, NPD 59 29.9) is "pretty bright, pretty large, round, brighter middle". The position precesses to RA 02 07 25.5, Dec +31 10 16, but there is nothing there. Two galaxies have been tentatively identified as IC 200: PGC 8064, a 15th-magnitude galaxy about 35 seconds of time to the west of Safford's position, and the considerably brighter PGC 7967, about 2 minutes of time to the west. As noted by Corwin, the nearer galaxy is probably too faint for Safford to have observed it, and Safford made a number of whole-minute errors in his records, so the 2 minutes of time error for PGC 7967 would be a more likely one than the fractional minute error for PGC 8064. Given that and the difference in brightness, PGC 7967 is by far the more likely candidate for what Safford observed, and is therefore treated as such in this entry; but since PGC 8064 is listed as IC 200 in some databases, it is discussed immediately following this entry. Based on a recessional velocity of 5275 km/sec, IC 200 is about 45 million light years away, in good agreement with a redshift-independent distance estimate of 235 million light years. Given that and its apparent size of 2.2 by 1.4 arcmin, it is about 155 thousand light years across.

(See IC 200 for a discussion of the misidentification.) Based on a recessional velocity of 3845 km/sec, PGC 8064 is about 180 million light years away. Given that and its apparent size of 0.65 by 0.65 arcmin, it is about 35 thousand light years across.

Stephane Javelle (557)
A 14th-magnitude spiral galaxy (type Sb?) in Cetus (RA 02 07 28.6, Dec +09 10 06)
Based on a recessional velocity of 9120 km/sec, IC 202 is about 425 million light years away, in fair agreement with redshift-independent distance estimates of 340 to 355 million light years. Given that and its apparent size of 1.4 by 0.2 arcmin, the galaxy is between 145 and 175 thousand light years across.

IC 204 (= PGC 8100)
Discovered (Oct 22, 1867) by
Truman Safford (98)
A 15th-magnitude spiral galaxy (type Sa?) in Cetus (RA 02 07 27.1, Dec -01 25 48)
Based on a recessional velocity of 11865 km/sec, a straightforward calculation indicates that IC 204 is about 550 million light years away. However, for objects at such distances we should take into account the Universal expansion during the time it took their light to reach us. Doing that shows that the galaxy was nearly 530 million light years away at the time the light by which we see it was emitted, just under 540 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of 0.6 by 0.45 arcmin, the galaxy is about 90 thousand light years across.

IC 205 (= PGC 8098)
Discovered (Dec 3, 1891) by
Stephane Javelle (76)
A 14th-magnitude spiral galaxy (type SB(s)a?) in Cetus (RA 02 07 27.4, Dec -02 05 29)
Based on a recessional velocity of 8345 km/sec, IC 205 is about 390 million light years away. Given that and its apparent size of 0.95 by 0.95 arcmin, it is about 105 thousand light years across.

IC 206 (= PGC 8238)
Discovered (Jan 26, 1892) by
Stephane Javelle (77)
A 14th-magnitude spiral galaxy (type SBdm?) in Cetus (RA 02 09 30.7, Dec -06 58 06)
Per Dreyer, IC 206 (Javelle #77, 1860 RA 02 00 34, NPD 97 41.7) is "pretty faint, small, irregularly round". The position precesses to RA 02 07 31.8, Dec -07 01 37, but there is nothing there. Per Corwin, IC 206 and 207's identities were determined from the fact that Javelle's positions for IC 206 and 207 have the same relative positions as two galaxies that match Javelle's descriptions. This suggested that Javelle might have used a reference star that was not the same as the one he thought he used. Per Thomson, it turns out that in both cases Javelle said he used CD-7 364 (J2000 RA 02 08 25.2, Dec -07 03 27) as his reference star, but must have actually used CD-7 372 (J2000 RA 02 10 23.6, Dec -07 00 02). The difference in the stars' positions led to an 1860 RA that was 1m 58s too small, and an NPD that was 3.6 arcmin too large. A corrected 1860 position for IC 206 (RA 02 02 32, NPD 97 38.1) precesses to RA 02 09 29.8, Dec -06 58 13, almost exactly on the galaxy listed above, so the identification is certain. Apparent size 0.95 by 0.45 arcmin.

IC 207 (= PGC 8251)
Discovered (Jan 26, 1892) by
Stephane Javelle (78)
A 14th-magnitude spiral galaxy (type S0/a pec?) in Cetus (RA 02 09 39.4, Dec -06 55 20)
Per Dreyer, IC 107 (Javelle #78, 1860 RA 02 00 43, NPD 97 39.0) is "pretty faint, small, irregularly round". The position precesses to RA 02 07 40.9, Dec -06 58 55, but there is nothing there. Per Corwin, IC 206 and 207's identities were determined from the fact that Javelle's positions for IC 206 and 207 have the same relative positions as two galaxies that match Javelle's descriptions. This suggested that Javelle might have used a reference star that was not the same as the one he thought he used.

The difference in the stars' positions led to an 1860 RA that was 1m 58s too small, and an NPD that was 3.6 arcmin too large. A corrected 1860 position for IC 207 (RA 02 02 41, NPD 97 35.4) precesses to RA 02 09 38.8, Dec -06 55 32, almost exactly on the galaxy listed above, so the identification is certain. Apparent size 2.1 by 0.45 arcmin.

IC 208 (= PGC 8167)
Discovered (Dec 3, 1888) by
Guillaume Bigourdan
A 13th-magnitude spiral galaxy (type SAbc?) in Cetus (RA 02 08 27.7, Dec +06 23 41)
Per Dreyer, IC 208 (Bigourdan #134, 1860 RA 02 01 08, NPD 84 18) is "very faint, pretty large, diffuse". The position precesses to RA 02 08 28.5, Dec +06 22 01, about 1.7 arcmin south of the galaxy, but the description fits, and the only other nearby object is the previously known NGC 825, so the identification is reasonably certain. Apparent size 1.4 by 1.35 arcmin.

A 13th-magnitude spiral galaxy (type SB(r)bc?) in Cetus (RA 02 08 58.7, Dec -07 03 32)
Per Dreyer, IC 209 (Javelle #79, 1860 RA 02 02 00, NPD 97 43.6) is "pretty bright, small, diffuse". The position precesses to RA 02 08 57.6, Dec -07 03 40, almost exactly on the galaxy, so the identification is certain. Apparent size 1.6 by 1.2 arcmin.

Aaron Skinner (101)
A 13th-magnitude spiral galaxy (type SBbc?) in Cetus (RA 02 09 28.3, Dec -09 40 49)
Per Dreyer, IC 210 (Safford #101, 1860 RA 02 02 32, NPD 100 20.3) has "no description". The position precesses to RA 02 09 25.0, Dec -09 40 25, less than an arcmin northwest of the galaxy, so the identification is certain. Apparent size 2.2 by 0.6 arcmin.

IC 217 (=

Discovered (Dec 7, 1893) by Stephane Javelle (and later recorded as IC 217)
"Discovered" (1896) by Lewis Swift (and later recorded as IC 1787)
A 14th-magnitude spiral galaxy (type Scd?) in Cetus (RA 02 16 10.5, Dec -11 55 37)
Per Dreyer, IC 217 (Javelle #563, 1860 RA 02 09 24, NPD 102 34.9) is "faint, pretty large, extended north-south". The position precesses to RA 02 16 12.0, Dec -11 55 45, nearly on the galaxy, so the identification is certain. (See IC 1787 for a discussion of the double listing.) Apparent size 2.45 by 0.6 arcmin.

IC 219 (= PGC 8813)
Discovered (Nov 17, 1887) by
Frank Muller (67)
A 13th-magnitude elliptical galaxy (type E3?) in Cetus (RA 02 18 38.8, Dec -06 54 13)
Based on a recessional velocity of 5050 km/sec, IC 219 is about 235 million light years away. Given that and its apparent size of 1.1 by 0.75 arcmin, it is about 75 thousand light years across. (Note: PGC 8816, the apparently smaller companion of IC 219, is a much more distant background galaxy, not a true companion, and twice the size of its nearer "neighbor".)

IC 219
A 16th-magnitude spiral galaxy (type SBbc?) in Cetus (RA 02 18 37.8, Dec -06 53 45)
(For images, see IC 219.) Based on a recessional velocity of 22605 km/sec, a straightforward calculation indicates that PGC 8816 is about 1050 million light years away. However, for objects at such distances we should take into account the Universal expansion during the time it took their light to reach us. Doing that shows that the galaxy was about 965 million light years away at the time the light by which we see it was emitted, about 1000 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of 0.55 by 0.25 arcmin, the galaxy is about 155 thousand light years across.

IC 225 (= PGC 9283 and perhaps =
NGC 867)
Possibly observed (Dec 21, 1783) by William Herschel (and later listed as NGC 867)
Discovered (Dec 29, 1893) by Stephane Javelle (566) (and later listed as IC 225)
A 14th-magnitude elliptical galaxy (type dE1?) in Cetus (RA 02 26 28.3, Dec +01 09 38)
Per Dreyer, IC 225 (Javelle #566, 1860 RA 02 19 15, NPD 89 27.8) is "faint, small, round, very little brighter middle, 14th magnitude star 2' northeast". The position precesses to RA 02 26 26.9, Dec +01 10 11, only half an arcmin northwest of the galaxy, so the identification is certain. (For the slight possibility that this is also NGC 867, see that entry.) Based on a recessional velocity of 1535 km/sec, IC 225 is about 70 million light years away, in good agreement with redshift-independent distance estimates of 55 to 70 million light years. Given that and its apparent size of 1.25 by 1.1 arcmin, it is about 25 thousand light years across.

A 14th-magnitude lenticular galaxy (type S0/a) in Cetus (RA 02 26 41.6, Dec -14 30 57)
Per Dreyer, IC 228 (Javelle #85, 1860 RA 02 20 01, NPD 105 08.4) is "very small, round, gradually brighter middle". The position precesses to RA 02 26 42.3, Dec -14 30 29, just north of the galaxy, so the identification is certain. (For a discussion of the duplicate listing and anything else, see NGC 944.)

IC 229
Recorded (1887) by
John Thome
Probably a 12th-magnitude star in Fornax (RA 02 27 23.8, Dec -23 50 09)
Per Dreyer, IC 229 (Thome (CD -24 1093), 1860 RA 02 21 02, NPD 114 27.0) is a "nebula, 10th magnitude". The position precesses to RA 02 27 22.9, Dec -23 49 11, but there is nothing there save for a 12th-magnitude star an arcmin to the south. The star is not separately recorded in the CD, so it is quite possible that it is what Thome observed, providing he made a one arcmin error in recording its declination. (A one minute correction to Thome's 1875 declination for CD -24 1093 puts the star only 0.6 seconds of time east of his corrected position, which is not much more than the average uncertainty of the Cordoba Durchmusterung's right ascensions.) Since single-digit errors are probably as common in the CD as in any other catalog, it is not at all unlikely that the star is IC 229. The difference in magnitude is no problem, as the CD listed all objects fainter than 10th magnitude as being exactly 10th magnitude, and the faintness of the star would have made it harder for Thome to determine its nature (in his 5-inch aperture objective a 12th-magnitude star would have been barely visible, and depending upon the quality of the night sky, more likely to be seen as a faint nebula than a definitely stellar object). Per Corwin, Dreyer took the object from one of the CD charts, where it was marked as a nebula, correctly measuring the position from the chart, but it cannot be a nebula as all of the nebulae in the area are too faint for Thome to have seen with his small objective. So IC 229 is either the star, or a nonexistent object.

IC 233 (= PGC 9622)
Discovered (Jan 6, 1894) by
Stephane Javelle
A 14th-magnitude spiral galaxy (type Sd?) in Cetus (RA 02 31 40.7, Dec +02 48 36)
Per Dreyer, IC 233 (Javelle #568, 1860 RA 02 24 24, NPD 87 48.8) is "pretty faint, small, round, a little brighter middle, very faint star 1' south". The position precesses to RA 02 31 39.2, Dec +02 48 33, right on the galaxy, and there is a 15th-magnitude star an arcmin to the south that makes the identification certain. Despite this, Corwin points out, many references misidentify PGC 9610 (the fainter galaxy right next to the star) as IC 233 (for which reason it is discussed immediately below). Based on a recessional velocity of 8245 km/sec, IC 233 is about 385 million light years away. Given that and its apparent size of 0.4 by 0.3 arcmins, it is about 45 thousand light years across. Since it is about the same distance and direction as PGC 9610, they may be a physical pair.

Given that and its apparent size of 0.25 by 0.2 arcmin, it is about 30 thousand light years across. Since it is about the same distance and direction as IC 233, they may be a physical pair.

IC 240
Recorded (Dec 9, 1890) by
Guillaume Bigourdan
Probably a group of four 15th- to 17th-magnitude stars in Perseus (RA 02 38 58.6, Dec +41 43 10)
Per Dreyer, IC 240 (Bigourdan #136, 1860 RA 02 30 11, NPD 48 53) is "very faint, pretty small". The position precesses to RA 02 39 04.4, Dec +41 43 32, but there is nothing there save for scattered stars, and at a few arcmin distance three previously known NGC objects. Per Corwin, Bigourdan's detailed notes seem to indicate an error in the offsets used to calculate the position of his #136, but an erratum reverses the error, yielding the values copied by Dreyer to the IC. So the detailed notes add nothing but confusion, save for a statement that the object is about 35 to 40 arcsec in size. This suggests that the line of four stars about 35 arcsec long and just over an arcmin west of the IC position is what Bigourdan observed, and although that identification cannot be regarded as certain, it seems the most likely.

IC 242
Recorded (Jan 26, 1892) by
Stephane Javelle
One of a pair of 16th-magnitude stars in Cetus (RA 02 38 23.9, Dec -06 56 02)
Per Dreyer, IC 242 (Javelle #88, 1860 RA 02 31 29, NPD 97 32.3) is "extremely faint, extremely small, very faint star close". The position precesses to RA 02 38 24.4, Dec -06 55 49, just north of the double star listed above. Per Corwin, Javelle's original notes read "nearly in contact with a very small star", and his good position for IC 243 (which see for an image), discovered by Javelle on the same night and less than 3 arcmin to the northeast, implies that his position for IC 242 should be equally good. Therefore IC 242 must be one of the two stars, and the other star must be the one nearly in contact with it; but which is which cannot be known.

IC 249 (=
NGC 1051 = NGC 961 = PGC 10172)
Discovered (Nov 27, 1880) by Édouard Stephan (and later listed as NGC 1051)
Discovered (1886) by Ormond Stone (and later listed as NGC 961)
Discovered (Jan 28, 1892) by Stephane Javelle (92) (and later recorded as IC 249)
A 13th-magnitude spiral galaxy (type SB(rs)m pec) in Cetus (RA 02 41 02.2, Dec -06 56 08)
Per Dreyer, IC 249 (Javelle #92, 1860 RA 02 34 06, NPD 97 32.4) is "pretty bright, very small, round, diffuse, 1051 to east", 1051 being NGC 1051 (which see for images and physical data). The position precesses to RA 02 41 01.2, Dec -06 56 15, right on the galaxy, so the identification is certain. Per Corwin the duplication with NGC 1051 occurred because Javelle thought the star superimposed on the northeastern side of the galaxy was the NGC object, and stated that his "new" object was definitely not the previously discovered nebula. (The duplicate entry for NGC 961 (which see for additional historical information) was due to Stone's position being well off the mark.)
