Multiwavelength light curve of HESS J0632+057. The data were folded with a period of 321 days. Zero phase has been arbitrarily defined at MJD 54 857. The grey circles are X-ray observations by Swift/XRT (0.3–10 keV) from Bongiorno et al. (2011). Top: the red circles are the EVN observations from this paper. The other radio data are from Skilton et al. (2009). The black circles (filled in grey) are Swift/XRT data obtained during the same cycle as the EVN data. Bottom: TeV emission from Acciari et al. (2009); Ong (2011); Mariotti (2011); Mukherjee (2011).
