First month on SN 2013ej
Listed in IVOA Registry (Virtual Observatory)
We present early photometric and spectroscopic observations of SN 2013ej, a bright Type IIP supernova (SN) in M74.
Description
SN 2013ej is one of the closest SNe ever discovered. The available archive images and the early discovery help to constrain the nature of its progenitor.
The earliest detection of this explosion was on 2013 July 24.125 ut and our spectroscopic monitoring with the FLOYDS spectrographs began on July 27.7 ut, continuing almost daily for two weeks. Daily optical photometric monitoring was achieved with the 1m telescopes of the Las Cumbres Observatory Global Telescope (LCOGT) network, and was complemented by UV data from Swift and near-infrared spectra from Public ESO Spectroscopic Survey of Transient Objects and Infrared Telescope Facility.

The data from our monitoring campaign show that SN 2013ej experienced a 10d rise before entering into a well-defined plateau phase. This unusually long rise time for a Type IIP has been seen previously in SN 2006bp and SN 2009bw. A relatively rare strong absorption blueward of H{alpha} is present since our earliest spectrum.
We identify this feature as SiII, rather than high-velocity H{alpha} as sometimes reported in the literature.
