Multi-Wavelength Observations of 1ES1959+650 in a Flaring State

In May 2002, the BL Lacertae object (BL Lac), 1ES1959+650, was detected in the Very High Energy (VHE) regime by the VERITAS collaboration using the Whipple γ-ray observatory. During the following two months, the VERITAS collaboration observed episodes of flaring; at times, the nightly average VHE signal was three times as bright as the Crab Nebula, the standard candle in VHE astronomy. 1ES1959+650 was also monitored in the optical and X-ray bands. The X-ray light curve showed periodic behavior and correlation with the VHE and the optical bands.
