Abstract

PKS 1510–089 is a Flat Spectrum Radio Quasar at z = 0.361 with radiative output dominated by the γ‐ray component and high variability over the whole electromagnetic spectrum. In particular, in the last two years very high γ‐ray activity was detected by AGILE with flaring episodes in August 2007 and March 2008 and an extraordinary activity during March 2009. Observations in optical/UV seems to indicate the presence of Seyfert‐like features in the broad band spectrum of PKS 1510–089, such as the little and big blue bumps. Moreover, X‐ray observations in March 2008 show a harder‐when‐brighter behaviour quite rare in FSRQs. We present the multiwavelength data of PKS 1510–089 collected by GASP‐WEBT, REM, Swift and AGILE during these γ‐ray flares.
