Tania Australis in Ursa Major. The blue-white star to the north is Tania Borealis or Lambda Ursae Majoris, actually a rather less luminous star much closer to the Sun than Tania Australis. Directly to the west of Tania Australis is the face-on spiral galaxy NGC 3184. Imagery provided by Aladin sky atlas
