  Type Ic supernovae, the explosions following the core collapse of massive
stars that have previously lost their hydrogen and helium envelopes, are
particularly interesting because of the link with long-duration gamma-ray
bursts. Although indications exist that these explosions are aspherical, direct
evidence has still been missing. Late-time observations of SN 2003jd, a
luminous Type Ic supernova, provide such evidence. Recent Subaru and Keck
spectra reveal double-peaked profiles in the nebular lines of neutral oxygen
and magnesium. These profiles are different from those of known Type Ic
supernovae, with or without a gamma-ray burst, and they can be understood if SN
2003jd was an aspherical, axisymmetric explosion viewed from near the
equatorial plane. If SN 2003jd was associated with a gamma-ray burst, we missed
the burst as it was pointing away from us.
