Near-infrared spectroscopy of the young SN Ia in NGC4424
Abstract
We report a near-infrared (NIR) spectrum obtained of the young SN Ia recently discovered in NGC 4424, PSN J12271283+0925132 (ATel #4115). The spectrum was acquired using the FIRE spectrometer on the 6.5-m Magellan I telescope on May 18.5 UT. We compare the spectrum to the SpeX spectrum of SN 2011fe (ATel #3599), the earliest NIR spectrum ever obtained for a SN Ia, at 2.6 days past the time of explosion.
