Spectroscopic and photometric observations of the nearby Type Ia Supernova ( SN Ia ) SN 2014J are presented .
Spectroscopic observations were taken -8 to +10 d relative to B -band maximum , using FRODOSpec , a multi-purpose integral-field unit spectrograph .
The observations range from 3900 Å to 9000 Å. SN 2014J is located in M82 which makes it the closest SN Ia studied in at least the last 28 years .
It is a spectrosopically normal SN Ia with high velocity features .
We model the spectra of SN 2014J with a Monte Carlo ( MC ) radiative transfer code , using the abundance tomography technique .
SN 2014J is highly reddened , with a host galaxy extinction of { E ( B - V ) } =1.2 ( R _ { V } =1.38 ) .
It has a \Delta m _ { 15 } ( B ) of 1.08 \pm 0.03 when corrected for extinction .
As SN 2014J is a normal SN Ia , the density structure of the classical W7 model was selected .
The model and photometric luminosities are both consistent with B -band maximum occurring on JD 2456690.4 \pm 0.12 .
The abundance of the SN 2014J behaves like other normal SN Ia , with significant amounts of silicon ( 12 % by mass ) and sulphur ( 9 % by mass ) at high velocities ( 12300 km s ^ { -1 } ) and the low-velocity ejecta ( v < 6500 km s ^ { -1 } ) consists almost entirely of ^ { 56 } Ni .
