What is it about?
MAGIC observed a Type Ia Supernova right after an extremely bright flare. This is the first time a Type Ia SN is observed at Very High Energies (teraelectronvolt)

Why is it important?
For the first time, upper limits on the very high energy emission of a Type Ia Supernova are established. The energy fraction isotropically emitted into TeV gamma rays during the first ~10 days for E>300 GeV is limited to 10^-6 of the total available energy budget. Within the assumed theoretical scenario, a power-law density profile of the ejecta is favoured, although this cannot discarded more sophisticated theoretical scenarios. The expected emission from SN 2014J, under these assumptions, would not increase enough in the near future to be detectable by any current or planned generation of IACTs.
Perspectives
MAGIC is a system of two 17m-diameter Imaging Atmospheric Cherenkov Telescopes located at the Canary island of La Palma, Spain, and designed to perform gamma-ray astronomy in the energy range from 50 GeV to greater than 50 TeV.
