cds-question@unistra.frsupernovaevisible-astronomyspectroscopyinfrared-photometrybroad-band-photometryWe present optical spectroscopic and photometric observations of the nearby type Ic supernova (SN Ic) SN 2014L. This SN was discovered by the Tsinghua-NAOC Transient Survey (TNTS) in the nearby type-Sc spiral galaxy M99 (NGC 4254). Fitting to the early-time light curve indicates that SN 2014L was detected at only a few hours after the shock breakout, and it reached a peak brightness of M_V_=-17.73+/-0.28mag (L=[2.06+/-0.50]x10^42^erg/s) approximately 13 days later. SN 2014L shows a close resemblance to SN 2007gr in the photometric evolution, while it shows stronger absorption features of intermediate-mass elements (especially CaII) in the early-time spectra. Based on simple modeling of the observed light curves, we derived the mass of synthesized ^56^Ni as M_Ni_=0.075+/-0.025M_{sun}_, and the mass and total energy of the ejecta as M_ej_=1.00+/-0.20M_{sun}_ and E_ej_=1.45+/-0.25 foe, respectively. Given these typical explosion parameters, the early detection, and the extensive observations, we suggest that SN 2014L could be a template sample for the investigation of SNe Ic.2018ApJ...863..109Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/863/109CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/183 : UBVRI Photometric Standards (Landolt 1992)J/A+A/508/371 : UBVRIJHK observations of SN 2007gr (Hunter+, 2009)J/ApJ/702/226 : Swift/UVOT panchromatic obs. of SN 2008D (Modjaz+, 2009)J/AJ/141/163 : Ultimate LC of SN 1998bw/GRB 980425 (Clocchiatti+, 2011)J/ApJ/741/97 : Light curves of Ibc supernovae (Drout+, 2011)J/AJ/146/86 : Cosmicflows-2 catalog (Tully+, 2013)J/ApJS/213/19 : Optical and near-IR light curves of 64 SNe (Bianco+, 2014)J/AJ/147/99 : Spectroscopy of 73 stripped core-collapse SNe (Modjaz+, 2014)J/AJ/148/1 : Optical and ultraviolet photometry of SN 2012fr (Zhang+, 2014)J/ApJS/220/20 : Si and Ca high-velocity features in SNe Ia (Zhao+, 2015)J/ApJ/821/57 : Photometry of the Type Ib/c SN2013ge (Drout+, 2016)J/ApJ/827/90 : Spectroscopy of SNe Ib, IIb and Ic (Liu+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/863/109https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/863/109http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/863/109https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/863/109https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/863/109http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/863/109GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap2.367228618189496e-19 6.118840631666147e-19InfraredOpticaldefaultJ/ApJ/863/109/table1UBVRI band photometry of SN 2014LTelTelescope (1)meta.id;instr.telcharBmag[16.1/19.1]?
