Variable compact galaxy VII Zw 768 = 3C371, at
R.A. 18h7.2m, Decl. +69°49'.
Fig 1a. 1 minute exposure on IIa-0 plate shows the nucleus of 3C371
indistinguishable from stars.
Fig 1b. 164 minute exposure on IIIa-J plates shows faint halo around
3C371 and numerous compact galaxies nearby.
Fig 1c. Isodensitometer tracing of plate b) shows luminous intergalactic
material [photos courtesy of H.C. Arp]. |

|
|
Fig d. 200-inch telescope plate, emulsion IIa-0 and
exposure of 5
minutes, obtained by Zwicky on July 16, 1965 shows VII Zw 768 = 3C371 as
a compact galaxy just distinguishable from stars of equal brightness. |
