IC 2650 (= PGC 1442333)
Discovered (Mar 27, 1906) by
Max Wolf (7-25)
A magnitude 15.2 spiral galaxy (type S pec?) in Leo (RA 11 14 52.4, Dec +13 51 10)
Based on a recessional velocity of 20205 km/sec, a straightforward calculation indicates that IC 2650 is about 940 million light years away. However, for objects at such distances we must take the expansion of the Universe during the time it took their light to reach us into account. Doing that shows that IC 2640 was about 870 million light years away when the light by which we see it left the galaxy, about 900 million years ago (the difference between the two numbers being due to the expansion of the Universe during that interval). Given that and the galaxy's apparent size of 0.4 by 0.3 arcmin, it is about 100 thousand light years across.

IC 2684 (= PGC 34438)

Max Wolf (7-59)
A magnitude 14.5 elliptical galaxy (type dE2?) in Leo (RA 11 17 01.0, Dec +13 05 59)
Based on a recessional velocity of 590 km/sec, IC 2684 is about 25 million light years away. (Although for such distances peculiar (non-Hubble expansion) velocities can substantially affect such estimates, no other distance estimate appears available, so it is hopefully better than nothing.) Given that and its apparent size of 0.7 by 0.6 arcmin, it is about 6 thousand light years across, implying that it is almost certainly a "dwarf" elliptical.

IC 2689 (= PGC 1419739)
Discovered (Mar 27, 1906) by
Max Wolf (7-64)
A magnitude 15.2 spiral galaxy (type Sc?) in Leo (RA 11 17 19.6, Dec +12 57 38)
Per Dreyer, IC 2689 (= Wolf list VII #64, 1860 RA 11 10 00, NPD 76 16.6) is "faint, small, extended 40". The position precesses to RA 11 17 19.2, Dec +12 57 35, right on the galaxy listed above, which also fits the description, so the identification is certain. Based on a recessional velocity of 6035 km/sec, IC 2689 is about 280 million light years away. Given that and its apparent size of 0.6 by 0.1 arcmin, it is about 50 thousand light years across.

IC 2690 (PGC 1420052)
Discovered (Mar 27, 1906) by
Max Wolf (7-65)
A magnitude 17(?) spiral galaxy (type Sa? pec) in Leo (RA 11 17 21.6, Dec +12 58 31)
Per Dreyer, IC 2690 (= Wolf list VII #65, 1860 RA 11 10 03, NPD 76 15.5) is "very faint, small, irregular figure, difficult". The position precesses to RA 11 17 22.2, Dec +12 58 41, only 0.2 arcmin northeast of the galaxy listed above, and since it is the only nearby object that Wolf could have seen on his plate the identification is certain. Based on a recessional velocity of 34405 km/sec, a straightforward calculation indicates that IC 2690 is about 1600 million light years away. However, for objects at such distances we must take the expansion of the Universe during the time it took their light to reach us into account. Doing that shows that IC 2640 was about 1400 million light years away when the light by which we see it left the galaxy, about 1480 million years ago (the difference between the two numbers being due to the expansion of the Universe during that interval). Given that and the galaxy's apparent size of 0.2 by 0.15 arcmin, it is about 80 thousand light years across.
