Technical data:
  • Name of the supernova: SN 2013ej/
  • Aparent Magnitud - visual (at the time of discovery): +13,5
  • Coordinates: right ascension- 1h 36m; declination 15º 45'.

  • Spectral typel: supernova type II.
Type II supernovas ocurr when a young massive star dies by rapidly collapsing and with a violent explosion. The outer layers are thrown away from the nucleuos of the star which in the process becomes a neutron star (very reduced size-merely a dozen of kilometers but extremelly dense).
