The distance to the fireworks galaxy NGC 6946 is highly uncertain. Recentdistance estimates using the tip of the red giant branch of 7.7 to 7.8 Mpc arelarger than the distance commonly assumed for studying supernovae in thisgalaxy of 5.9 Mpc. Here we use the high supernova rate of the galaxy to derivethe star-formation rate and predict the galaxy's FUV flux. We also account fordust extinction by different methods to derive a distance of 7.9+/-4.0 Mpc forNGC 6946. We then use the new distance to re-evaluate the understanding of thesupernova progenitors 2002hh, 2004et, 2017eaw, the possible electron captureevent 2008S and the possible black-hole forming event N6946-BH1. For the lattertwo exotic events the new distance improves the consistency between theobserved progenitors and the stellar models that give rise to these events.From our findings we strongly recommend that all future studies of NGC~6946must use the greater distance to the galaxy of 7.72+/-0.32 Mpc of Anand et al.(2018).
