NGC 5939 - Intermediate Spiral Galaxy in Ursa Minor

Above the horizon.  Circumpolar today
Alt: 30.41°   Az: 355.34°   Direction: North

NGC 5939 is a Intermediate Spiral Galaxy in the Ursa Minor constellation. NGC 5939 is situated close to the northern celestial pole and, as such, it is visible for most part of the year from the northern hemisphere. Given its B magnitude of 13.7, NGC 5939 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 5939 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).
