The HESS experiment, an array of four Imaging Atmospheric Cherenkov Telescopes with high sensitivity and large field-of-view, has been used to search for emitters of very-high-energy (VHE, >100 GeV) γ-rays along the Galactic plane, covering the region 30° 60°, 280° 330°, and -3° 3°. In this continuation of the HESS Galactic Plane Scan, a new extended VHE γ-ray source was discovered at =19h12m49s, =+10°09´06´´(HESS J1912+101). Its integral flux between 1–10 TeV is ~10% of the Crab Nebula flux in the same energy range. The measured energy spectrum can be described by a power law d with a photon index . HESS J1912+101 is plausibly associated with the high spin-down luminosity pulsar PSR J1913+1011. We also discuss associations with an as yet unconfirmed SNR candidate proposed from low frequency radio observation and/or with molecular clouds found in 13CO data.
