IC 2600

IC 2602 = OCL 838 = the Southern Pleiades
Discovered (1751) by Nicolas Lacaille
A 2nd-magnitude open cluster in Carina (RA 10 42 56.5, Dec -64 23 39)
Per Dreyer, IC 2602 (= Bailey, 1860 RA 10 38 00, NPD 153 39) is a "cluster, coarse, including θ Carinae". The attribution to Solon Bailey is based on his 1896 observation; but Lacaille had recorded the cluster nearly a century and a half earlier (as his list II, number 9), and is now credited as the discoverer. However, Dreyer's description and 1860 position are undoubtedly based on Bailey's report. The position precesses to RA 10 42 59.8, Dec -64 23 00, about an arcminute northeast of θ Carinae, whose position is used for that of the cluster (above), so the identification is certain. IC 2602 consists of about 60 upper Main Sequence stars scattered across a degree wide region. At the cluster's 480 light year distance, this corresponds to a diameter of about 10 light years. Other than 3rd-magnitude θ Carinae, the brightest cluster members are about 5th magnitude. The cluster is thought to be about 50 million years old. |

IC 2603
Recorded (Mar 27, 1887) by Guillaume Bigourdan (279)
IC 2604 (= PGC 32390)
Discovered (May 7, 1896) by Stephane Javelle (1163)
A 14th-magnitude barred spiral galaxy (type SB(s)m pec?) in Leo Minor (RA 10 49 25.0, Dec +32 46 21)
Based on a recessional velocity of 1635 km/sec, IC 2604 is about 75 million light years away. Given that and its apparent size of 1.2 by 0.85 arcmin, it is about 25 thousand light years across. |
