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) -rays along the Galactic plane, covering the region 30°<b < 60°, 280°<b < 330°, and -3°<b < 3°. In this continuation of the HESS Galactic Plane Scan, a new extended VHE -ray source was discovered at =191249, =+10°09′b <06AA(HESS J1912+101). Its integral flux between 1-10 b <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 CO data.
