We report the discovery by LSQ and classification by Carnegie Supernova Project II of two targets:
LSQ ID Discovery RA Dec Disc. Mag Instrument Spectra Date Type z Details
LSQ13pf March 21.333 13:48:14.34 -11:38:38.7 19.5 FIRE NIR March 25 Ia 0.085 +/- 0.05 1 day before max light
LSQ13lo March 18.265 14:26:38.79 +03:30:11.5 19.8 FIRE NIR March 25 0.08 +/- 0.05 Striped envelope , core-collapse SN,
soon after maximum light.
Characteristic features include the
CaII IR3 at about 13000 km/s,
the plateau-like feature from 0.88
to 0.96 microns and the broad
absorption feature with a square
bottom from 1.00-1.05 microns.
