  We present the optical (UBVRI) and ultraviolet (Swift-UVOT) photometry, and
optical spectroscopy of Type Ia supernova SN 2017hpa. We study broadband
UV+optical light curves and low resolution spectroscopy spanning from $-13.8$
to $+108$~d from the maximum light in $B$-band. The photometric analysis
indicates that SN 2017hpa is a normal type Ia with $\Delta m_{B}(15) =
0.98\pm0.16$ mag and $M_{B}=-19.45\pm0.15$ mag at a distance modulus of $\mu =
34.08\pm0.09$ mag. The $(uvw1-uvv)$ colour evolution shows that SN 2017hpa
falls in the NUV-blue group. The $(B-V)$ colour at maximum is bluer in
comparison to normal type Ia supernovae. Spectroscopic analysis shows that the
Si II 6355 absorption feature evolves rapidly with a velocity gradient,
$\dot{v}=128\pm 7$ km s$^{-1}$ d$^{-1}$. The pre-maximum phase spectra show
prominent C II 6580 {\AA} absorption feature. The C II 6580 {\AA} line velocity
measured from the observed spectra is lower than the velocity of Si II 6355
{\AA}, which could be due to a line of sight effect. The synthetic spectral
fits to the pre-maximum spectra using syn++ indicate the presence of a high
velocity component in the Si II absorption, in addition to a photospheric
component. Fitting the observed spectrum with the spectral synthesis code
TARDIS, the mass of unburned C in the ejecta is estimated to be $\sim
0.019$~$M_{\odot}$. The peak bolometric luminosity is $L^{bol}_{peak} =
1.43\times10^{43}$ erg s$^{-1}$. The radiation diffusion model fit to the
bolometric light curve indicates $0.61\pm0.02$ $M_\odot$ of $^{56}$Ni is
synthesized in the explosion.
