The Baryonic Tully-Fisher Relation is an empirical scaling relation between the baryonic mass and rotational velocity of a disk galaxy. One primary source of scatter within the BTFR arises from uncertainties in galaxy distances used to derive masses. To minimize distance uncertainties, we construct the BTFR for supernova host galaxies with well-constrained redshift-independent distances. We are pursuing an observing campaign at the Green Bank Observatory, yielding us 132 observing hours to obtain HI spectra for 220 galaxies without. Once obtained, we will reduce and analyze the spectra and combine this with archival spectra to generate a more correlated template BTFR.
