PGC 37282 (with
PGC 200275 = Arp 62)
A 14th-magnitude spiral galaxy (type SBcd pec?) in Ursa Major (RA 11 53 40.0, Dec +43 27 40)

There is some confusion in database listings for Arp 62, but no doubt as to what the correct object is. NED lists PGC 37282 or UGC 06865 as Arp 62, the northern component (identified by its position) as UGC 06865 NED02, and the southern component (identified by its position) as UGC 06865 NED01. LEDA identifies the northern component as Arp 62 and PGC 37282, and the other component as UGC 06865, or PGC 200275; however, it gives the same coordinates for both components, namely the position of PGC 37282. So although it is reasonable and probably appropriate to call the southern component PGC 200275, the data for that object have been obtained only from the NED.
     Based on a recessional velocity of 5955 km/sec and an overall apparent size of 1.65 by 0.4 arcmin (including the portions extending past its apparent companion), PGC 37282 is about 275 million light years away, and about 135 thousand light years across. The overall structure is listed as type S? and the northern portion as type SB in NED, and as type Scd in LEDA, hence the combined tentative listing of the type in the initial entry.

PGC 200275 (with
PGC 37282 = Arp 62)
Listed here since its association with PGC 37282 is the basis for Arp 62
A 16th-magnitude compact galaxy (type E3(c)?) in Ursa Major (RA 11 53 38.0, Dec +43 27 11)

Note: LEDA gives the same position for PGC 200275 as for PGC 37282, which see for images; so only the LEDA designation is used here. The position and physical data are taken from NED (which lists this object as UGC 06865 NED01). The recessional velocity of 5770 km/sec is close enough to that for PGC 37282 to consider the two objects to be at the same distance, and given their appearance, they are probably a physically interacting pair. Given their distance (about 275 million light years), the 0.15 by 0.1 arcmin apparent size of PGC 200275 corresponds to about 12 thousand light years.
