Corwin's Notes

===== NGC 5506, a peculiar edgewise spiral with a strong dust lane and a "thick" disc, is a well-known radio and x-ray source (see e.g. NED for details). It's companion, NGC 5507, is a smooth, apparently unperturbed S0^0, radio-quiet and, while it has also been detected in x-ray surveys, is a much fainter x-ray source. Since both are at the same distance, and probably at least mildly interacting, the contrast of their physical properties is striking.

Steve's Notes

===== NGC 5506 17.5" (4/4/92): moderately bright, moderately large, edge-on 5:1 E-W, 3.0'x0.6', broad concentration. Located 11' NE of mag 7.9 SAO 139790. Forms a pair with NGC 5507 3.7' NNE. This is a Seyfert and Markarian galaxy.
