We report the spectroscopic classification of OGLE-2014-SN-014 using a near-infrared spectrum (range 800-2500 nm) obtained on Feb 15.02 UT with the FoldedPort Infrared Echellette (FIRE) spectrograph on the 6.5-m Magellan Baade Telescope at Las Campanas Observatory. The near-infrared spectrum shows strong P-Cyg lines of He I. Placed at the rest frame using a redshift of z=0.05, the spectrum of OGLE-2014-SN-014 resembles the FIRE spectrum of LSQ13cum taken a few days past maximum light. LSQ13cum was classified as a type-Ib supernova with an optical spectrum taken near maximum light (ATEL #5561).

OGLE-2014-SN-014 was discovered by OGLE-IV (ATel #4495) with an image taken on Feb 12.21, 2014 at 19.0 mag. Note that OGLE-2014-SN-014 is situated in the same galaxy (2MASX J04272268-7442059) as OGLE-2013-SN-017 (ATel #4859) discovered on Mar 3.12, 2013. OGLE-2013-SN-017 was classified as a type-IIn supernova at z=0.043 (ATel #4863). The two supernovae are 6.36 arcsec apart in angular distance.
