Below the horizon.  Never rises today
Alt: -40.48°   Az: 108.01°   Direction: East-South-East

NGC 4603A is a Galaxy in the Centaurus constellation. NGC 4603A is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its B magnitude of 14.24, NGC 4603A is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

The image below is a photograph of NGC 4603A from the Digitized Sky Survey 2 (DSS2 - see the credits section) taken in the red channel. The area of sky represented in the image is 0.5000x0.5000 degrees (30.00x30.00 arcmins).
