VHE gamma-ray emission was discovered from the high-frequency-peaked BL Lac object RGB J0152+017 in November 2007. The instantaneously triggered multiwavelength observations with the X-ray satellites Swift and RXTE, the optical telescope ATOM and the radio telescope Nancay provided the first simultaneous SED for RGB J0152+017. While these and further observations with H.E.S.S. gives no indication for variability, the follow-up observations until January 2008 with Swift (X-ray and UV-optical telescope) and ATOM (optical) show flux variations on time scales of {approx}10 days with different variability patterns. This non-monotonically flux variation of the simultaneous multiwavelength observations lead to the conclusion that the shape of the synchrotron spectrum changes.
