Monitoring FSRQs with MAGIC: the case of PKS1510-089

Among the VHE extragalactic γ-ray emitters, blazars are the most favorably detected by the stereoscopic Imaging Air Cherenkov Telescopes system of MAGIC. Sensitive to gamma-ray energies down to 50 GeV, MAGIC strongly contribute to increase their census, particularly with the type of Flat Spectrum Radio Quasars. Standing out as highly redshifted emitters of the blazar class, they are characterized by softer VHE γ-ray spectra and are favorably detected during short flares, making their multiwavelenght monitoring crucial. PKS1510-089, detected by MAGIC also over extended periods, provides an interesting case of study for the low state of these sources. An overview of the source MWL monitoring program will be given along with a resume of its quiescent state observation with MAGIC during the 2015-2016 period.
