Simultaneous Multiwavelength observation of Mkn 501 in a low state in 2006

Understand

We present results of the multiwavelength campaign on the TeV blazar Mkn 501 performed in 2006 July, including MAGIC for the VHE gamma-ray band and Suzaku for the X-ray band.

• A VHE gamma-ray signal was clearly detected with an average flux above 200 GeV of ~20 % of the Crab Nebula flux, which indicates a low state of source activity in this energy range.
• No significant variability has been found during the campaign.
• The VHE gamma-ray spectrum can be described by a simple power-law from 80 GeV to 2 TeV with a photon index of 2.8+/-0.1, which corresponds to one of the steepest photon indices observed in this energy range so far for this object.
