We present well-sampled $UBVRIJHK$ photometry of SN 2002fk starting 12 daysbefore maximum light through 122 days after peak brightness, along with aseries of 15 optical spectra from -4 to +95 days since maximum. Ourobservations show the presence of C II lines in the early-time spectra of SN2002fk, expanding at ~11,000 km s$^{-1}~$ and persisting until ~8 days pastmaximum light with a velocity of $\sim$9,000 km s$^{-1}~$. SN 2002fk ischaracterized by a small velocity gradient of $\dot v_{Si~II}=26$ km s$^{-1}$day$^{-1}$, possibly caused by an off-center explosion with the ignition regionoriented towards the observer. The connection between viewing angle of anoff-center explosion and the presence of C II in the early time spectrumsuggests that the observation of C II could be also due to a viewing angleeffect. Adopting the Cepheid distance to NGC 1309 we provide the first $H_{0}$value based on near-IR measurements of a Type Ia supernova between 63.0$\pm$0.8 ($\pm$ 2.8 systematic) and 66.7$\pm$1.0 ($\pm$ 3.5 systematic) km/s/Mpc,depending on the absolute magnitude/decline rate relationship adopted. Itappears that the near-IR yields somewhat lower (6-9 %) $H_0$ values than theoptical. It is essential to further examine this issue by (1) expanding thesample of high-quality near-IR light curves of SNe in the Hubble flow, and (2)increasing the number of nearby SNe with near-IR SN light curves and preciseCepheid distances, which affords the promise to deliver a more precisedetermination of $H_0$.
