This page has displayed the optical image of comet 2013R1 Lovejoy positioned in northern part of Bootes of dawn northeast skies, and its spectrogram taken with an amateur-oriented spectrometer.
Same as other many comets, coma of the comet has emission bands of carbon molecular (C2, C3) called "swan band", moreover lines of the cyan (CN), the radical of ammonia (NH2), and so on.
  The 1st optical image: View angle: 1.5×2.3°
