Archival HST data taken in F606W+F814W of two different fields in the outerregions of NGC 6946 is used to measure a tip of the red giant branch (TRGB)distance to the galaxy. We employ a Bayesian maximum-likelihood modeling methodthat incorporates the completeness of the photometry, and allows us to modelthe luminosity function of the RGB population. Our two fields provide us withdistances of 7.74 $\pm$ 0.42 Mpc and 7.69 $\pm$ 0.50 Mpc, respectively. Ourfinal distance of 7.72 $\pm$ 0.32 Mpc is higher than most values publishedpreviously in the literature. This has important implications for supernovameasurements, as NGC 6946 is host to the most observed supernovae (10) of anygalaxy to date. We find that the supernovae in NGC 6946 are on average $\sim$2.3 times more luminous than previous estimates. Our distance gives NGC 6946 apeculiar velocity of $v_{pec}$ = $-229$ $\pm$ $29$ km/s in the Local Sheetframe. This velocity is the projected component of a substantial negative SGZmotion, indicating a coherent motion along with the other members of the M101wall toward the plane of the Local Sheet. The M101 wall, a spur off the LocalSheet into the Local Void, is experiencing the expansion of the Local Void.
