Description
The active galactic nucleus PG 1553+113 was observed by the MAGIC
telescope in July 2006 during a multiwavelength campaign, in which
telescopes in the optical, X-ray, and very high energies participated.
Although the MAGIC data were affected by strong atmospheric absorption
(calima), they were analyzed after applying a correction. In 8.5 h, a
signal was detected with a significance of 5.0σ. The integral flux
above 150 GeV was (2.6±0.9)× 10-7 ph s-1
m^{-2}. By fitting the differential energy spectrum with a power
law, a spectral index of -4.1±0.3 was obtained.
