Abstract:
We present photometric and spectroscopic observations at optical and
near-infrared wavelengths of the nearby type-Ic supernova 2007gr.
These represent the most extensive data-set to date of any supernova
of this sub-type, with frequent coverage from shortly after discovery
to more than one year post-explosion.
Description:
UBVRI photometry of SN 2007gr was obtained from 2007 Aug. 18 to 2008
Sep. 30, spanning approximately -6 to +404 days with respect to B-band
maximum.
Optical spectra were obtained at 29 epochs, spanning -7.3 to +375.5
days with respect to B maximum.

Note (3): The instrumental resolution for the Gemini spectra was derived as
the range of Gaussian FWHMs measured for a number of unblended arc
lines. The resolution of the TNG spectra have been estimated using the
FWHM of the night sky lines.
