Discovery of VHE gamma-rays from the BL Lac RGB J0152+017 — •Dalibor Nedbal1, Sarah Kaufmann2, Martin Raue1, and Stefan Wagner2 for the H.E.S.S. collaboration — 1Max-Planck-Institut fuer Kernphysik, Heidelberg, Germany — 2Landessternwarte, Heidelberg, Germany
The BL Lac RGB J0152+017 (z=0.08) was observed from October to December 2007 by the H.E.S.S. array of four atmospheric Cherenkov telescopes. A significant VHE (E>100GeV) gamma-ray signal from the direction of RGB J0152+017 was found in the on-site analysis, which showed an indication for variability on nightly bases. The discovery by H.E.S.S. triggered ToO X-ray observations by the SWIFT and RXTE satellites. The object was additionaly monitored by the optical telescope ATOM. The result from the HESS and MWL observations will be presented.
