NGC 6872 = ESO 073-IG032 = VV 297a = AM 2011-705 20 16 56.9 -70 46 04 V = 11.8; Size 6.0x1.5; SB = 14.0; PA = 66d 18" (7/10/02 - Magellan Observatory, Australia): second brightest in the Pavo Group with brightest member N6876. This huge barred spiral (with excessively distended arms spanning roughly 750,000 light years) appeared moderately bright, fairly small, elongated 2:1 SW-NE in the direction of a mag 10.4 star 1.1' WSW of center, ~1.2'x0.6', broad concentration with a brighter core. Interacting with IC 4970 at 1.1' N just outside the halo while fainter PGC 64439 lies 4.0' SE. Other members of the group include N6876, N6877, N6880. 18" (7/8/02 - Magellan Observatory, Australia): moderately bright, elongated 2:1 SW-NE toards a mag 10.5 star off the SW edge, 1.2'x0.5'. Fairly well concentrated with a small bright core. In 1979A&A, 79, 22, the abstract for "NGC 6872 - A remarkable barred spiral" mentions "The extent of the arms is probably greater than in any other spiral known; it is concluded that NGC 6872 is a conventional barred spiral in which severe tidal interaction took place."
