IC 938 - Spiral Galaxy in Ursa Major
IC 938 is a Spiral Galaxy in the Ursa Major constellation. IC 938 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere.
- IC 938 is above the horizon from Greenwich, United Kingdom [change]. Its current altitude is 63° above the horizon. See also rise and set times.
- Given its B magnitude of 16.5, IC 938 is visible only through long exposure photography.
