Based on recessional velocity of 10420 km/sec, about 460 million light years away. Given that and apparent size of 0.8 by 0.8 arcmins, about 110 thousand light years in diameter.

Based on recessional velocity of 7400 km/sec, about 330 million light years away. Given that and apparent size of 0.4 by 0.4 arcmins, about 40 thousand light years across.

Based on recessional velocity of 7255 km/sec, about 325 million light years away. Given that and combined apparent size of 0.6 by 0.4 arcmins, the pair is about 55 thousand light years across.

Based on recessional velocity of 7330 km/sec, about 325 million light years away. Given that and combined apparent size of 0.3 by 0.25 arcmins, about 30 thousand light years across. Given similar direction and distance, perhaps gravitationally bound to NGC 1065.

(HyperLeda and Wikisky mistakenly identify this object as NGC 1065, the brighter galaxy northeast of IC 254. The objects are correctly labeled on the wide-field image below.) Apparent size 0.4 by 0.35 arcmin; nothing else available.

An unusually faint galaxy for an NGC/IC object, but per Corwin and Steinicke, almost certainly the object Swift observed, on the same night he discovered the nearby but much brighter galaxies, IC 257 and 260.

Per Corwin: Leavenworth's right ascension was off by a minute, so Javelle's correct position appeared to be a different object, hence the double listing. However, the descriptions are identical, so there is no doubt of their being the same object.

(Considering Corwin's discussion and the appearance of the Wikisky images, Swift may have thought the western pair of galaxies was a nebula, and the eastern galaxy a close star; but there are other educated guesses as to which galaxy or galaxies he actually observed. As a result, the listing is generally considered to apply to the entire triplet of galaxies.) Component 2 (PGC 11389) has a recessional velocity of 9735 km/sec, suggesting a distance of 435 million light years for the triplet (presuming they are all at the same distance). Otherwise, very little information is directly available. Based on the Wikisky images below, Component 1 (= PGC 11388) has an apparent size of 0.15 by 0.15 arcmin, and if at the suggested distance, is about 20 thousand light years across. Component 2 has an apparent size of 0.4 by 0.25 arcmin, and must be about 50 thousand light years across. Component 3 (= PGC 11390) has an apparent size of 0.2 by 0.15 arcmin, and if at the suggested distance, is about 25 thousand light years across. (Note: Wikisky shows PGC 11389 as the identification for all three galaxies, so the galaxies' positions were used to label the closeup image.)

Per Corwin, the positions and descriptions by Parsons and Swift are so similar that the failure to realize the "two" objects were the same must have been a simple oversight by Swift and Dreyer.

Per Corwin, Swift's right ascension is off by a minute, hence the double listing; but the descriptions (and lack of any object at the incorrect position) make it clear that the two objects are the same.

Per Corwin, an earlier speculation that IC 286 might be NGC 1202 is wrong. Several efforts have been made to find a field of view similar to Bigourdan's description, assuming various errors in his measurement or recording of the position. To date, none have succeeded.

Per Corwin, Swift discovered several nebulae on 11 September 1888, but his positions were not very accurate, so when Barnard observed the area a few years later, he thought he had discovered previously unknown objects. His positions were accurate, and therefore different from Swift's, so when he sent them to Dreyer they were given separate listings. These comments also apply to IC 292, IC 293, and IC 294, and to a certain extent, IC 295 and IC 296.

See IC 290 for a discussion of the problems with Swift's observations in this region. Steinicke lists this and IC 296 as identical to IC 294, but Corwin notes that Barnard found only five nebulae in the region, while Swift recorded seven, and feels that IC 295 almost certainly does not exist, and IC 296 may or may not be the same as IC 294.

Also designated Arp 147, in the Atlas of Peculiar Galaxies. IC 298 is a pair of peculiar galaxies almost certainly created by a galactic collision, in which one galaxy (component 2) passed through the center of the other (component 1), removing its core and triggering a starburst in the remaining portion of the galaxy, which formed a circular ring of hot, bright stars and heated gases. Component 2 also suffered considerable distortion and disturbance near its core, but was left looking far more normal. The odd result is a pair of galaxies which look like the numbers "1" and "0", placed side by side in the sky. Based on a recessional velocity of 9655 km/sec, the pair is about 430 million light years away. Given that and an apparent size of 0.4 by 0.3 arcmin, Component 1 is about 50 thousand light years across, while Component 2, with an apparent size of 0.5 by 0.2 arcmin, is about 60 thousand light years from end to end. Note: Steinicke lists component 2 as PGC 11893, or IC 298A. That designation applies to a different galaxy, as shown in the wide-field image below

Apparent size 0.7 by 0.5 arcmin; nothing else appears to be available.
