NGC 4615 = Arp 34 is a spiral galaxy with extensive star formation regions of the Hubble type Scd in the constellation Haar der Berenike in the northern sky. It is estimated to be 211 million light-years from the Milky Way and about 100,000 light years in diameter.
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class spiral galaxies with the shape of an integral sign (Arp catalog) . In the same area of the sky are u. a. the galaxies NGC 4613 , NGC 4614 , IC 3644 , IC 3646 .
The Type IIn supernova SN 1987F was observed here.
