Spiral Galaxy in Hydra

Uploaded 2/6/02

One of the brightest galaxies in northern Hydra, this 11.0 magnitude type Sa spiral has tight and very delicate arms. It is listed as 4.2 x 3.4 in size, and hosts a plethora of faint field galaxies in the background. This galaxy is quite yellow from core to outer disk, with a B-V index of .9. A few bluish knots can be faintly seen on its primarily yellowish disk, and no HII regions are visible.
