In the course of surveying spiral galaxies in the Local Volume, long exposures of NGC 3416 show two probable stellar streams with the possible remnant of a satellite galaxy. I captured the discovery image using the Schulman Telescope at Steward Observatory's Mount Lemmon Sky Center (University of Arizona). I acquired the wide bandpass data over three nights under photometric conditions in 2015 February. Prominent theories of galaxy formation hold that the creation of present-day galaxies are the aggregation of many past minor mergers. Stellar streams lend credence to the idea by presenting evidence of extended low surface brightness tidally created signatures. NGC 3614 appears to be a good example the for kind of extended features expected by these theories.
