Corwin's Notes

===== NGC 6365. Swift's RA is 1 minute, 7 seconds too small, and his comment "B * nr sf" should read "B * nr nf". Aside from that, the interacting pair matches his description pretty well.

Steve's Notes

===== NGC 6365 24" (6/28/16): at 375x; NGC 6365A is the southern and brighter member of Arp 30. At 375x it appeared faint to fairly faint, fairly small, slightly elongated, 40"x35", weak concentration. NGC 6365B (perhaps Arp's "heavy arm"), attached at the northwest edge, appeared extremely faint to very faint, edge-on ~3:1 SSW-NNE, ~30"x10", very low surface brightness so difficult to judge size. A distracting mag 10.2 star is ~1.5' NE and a 6" pair of mag 14-15 stars is 1' NE. 48" (5/15/12): NGC 6365A is fairly faint, moderately large, round, ~50" diameter, broad concentration with a brighter core. NGC 6365B is attached at the NW edge and appears faint, edge-on 4:1 NNW-SSE, 0.6'x0.15', low surface brightness, very weak concentration. . The pair is 1.6' SW of a mag 10.2 star that detracts somewhat from viewing. A mag 14-15 pair at 6" separation lies just 1' NNE. 17.5" (7/16/88): this is a double galaxy (Arp 30) with a separation of 30" oriented NNW-SSE with the brighter component at the SSE end. NGC 6365A is very faint, small, weak concentration, very diffuse. Bracketed by two mag 14 stars off the SW and NE ends. NGC 6365B is attached at the NW end of NGC 6365A and appears extremely faint, small, very elongated SW-NE [1.1x0.2], requires averted vision.
