Simultaneous multiwavelength observations of the blazar 1ES1959+650 at a low TeV flux

Understand

We present the results from a multiwavelength campaign on the TeV blazar 1ES 1959+650, performed in May, 2006.

• Data from the optical, UV, soft- and hard-X-ray and very high energy (VHE) gamma-ray (E > 100 GeV) bands were obtained with the SUZAKU and SWIFT satellites, with the MAGIC telescope and other ground based facilities.
• The source spectral energy distribution (SED), derived from SUZAKU and MAGIC observations at the end of May 2006, shows the usual double hump shape, with the synchrotron peak at a higher flux level than the Compton peak.
• With respect to historical values, during our campaign the source exhibited a relatively high state in X-rays and optical, while in the VHE band it was at one of the lowest level so far recorded.
