We present the results of the multiwavelength observation of the high frequency-peaked BL Lac object 1ES1426+428 carried in May-June 2008 with the KVA telescope for the optical band, the Swift and Suzaku satellites for the X-ray band and the MAGIC telescope for the very high energy band (E>100 GeV). The optical flux increased by 20% during the observation, while X-ray data show that the source was in an intermediate state of activity. MAGIC did not detect a significant gamma-ray emission from the source, so we report flux Upper Limit at 95% CL for energies above 130 GeV. A Spectral Energy Distribution is also obtained combining the data from the 2008 campaign with the historical ones.

Abstract
We present the results of the multiwavelength observation of the high frequency-peaked BL Lac object 1ES1426+428 carried in May-June 2008 with the KVA telescope for the optical band, the Swift and Suzaku satellites for the X-ray band and the MAGIC telescope for the very high energy band (E>100 GeV). The optical flux increased by 20% during the observation, while X-ray data show that the source was in an intermediate state of activity. MAGIC did not detect a significant gamma-ray emission from the source, so we report flux Upper Limit at 95% CL for energies above 130 GeV. A Spectral Energy Distribution is also obtained combining the data from the 2008 campaign with the historical ones.
