Abstract (from CDS):

Detection of a γ-ray source above 300 GeV is reported, confirming the unidentified source MGRO J1908+06, discovered by the Milagro collaboration at a median energy of 20TeV. The source was observed during 27h as part of the extension of the HESS Galactic plane survey to longitudes >30°. HESS J1908+063 is detected at a significance level of 10.9σ with an integral flux above 1 TeV of (3.76±0.29stat±0.75sys)x10–12ph/cm2/s, and a spectral photon index Γ= 2.10±0.07stat±0.2sys. The positions and fluxes of HESS J1908+063 and MGRO J1908+06 are in good agreement. Possible counterparts at other wavelengths and the origin of the γ-ray emission are discussed. The nearby unidentified GeV source, GRO J1908+0556 (GeV) which also remains unidentified and the new Fermi pulsar 0FGL J1907.5+0617, may be connected to the TeV source.
