Abstract
Observations of the HBL blazar 1RXS J023832.6-311658 were made in 2013, 2015 and 2016 with the High Energy Stereoscopic System (H.E.S.S.). An excess of very high energy (VHE: > 100 GeV) gamma rays is clearly observed. The spectral energy distribution including the VHE spectrum will be presented. This object has a hard spectrum at TeV energies, and has a redshift z=0.23. These characteristics could be suitable for extragalactic magnetic fields for which the perspectives with H.E.S.S. will be discussed.
