PKS 2005-489 is a very extreme high-frequency peaked BL Lac object which shows at its detection in VHE gamma-rays the softest TeV spectrum ever measured. Multi-year studies show large flux and spectral variation in the X-ray regime while only weak variations have been detected in the VHE band. In 2009, PKS 2005-489 exhibited a very strong flare in the synchrotron regime which was covered by our broadband multi-wavelength campaign. With the simultaneous observations by HESS (TeV), Fermi/LAT (GeV), RXTE (keV), Swift (keV, UV, optical) and ATOM (optical) the synchrotron and inverse Compton emission peaks were well covered. With all these observations the upper end of both spectral components in the X-ray and TeV regime was measured in several epochs while a variation by a factor of 50 was detected in the X-rays. We will present the results of the new multi-wavelength campaign during the synchrotron flare and discuss the broadband characteristics in respect to earlier observations of lower states.
