Based on UBVR photometry, the star was determined to most likely be an early G-type supergiant star.

In May 2017, supernova SN 2017eaw was first observed to be 12.8 magnitude in the northwest region of the galaxy and light curves obtained over the next 600 days showed that it was a Type II-P. The progenitor was determined to have been a ~15 M☉ red supergiant before going nova.
