Query: VERITAS Blazar Observations - Recent Results   We present the discovery of very high energy (VHE) gamma-ray emission from
the high-frequency-peaked BL Lac object 1ES 0806+524 (z=0.138) and the
intermediate-frequency-peaked BL Lac object W Comae (z=0.102) with VERITAS. VHE
emission was discovered from these objects during the 2007/2008 observing
campaign, with a strong outburst from W Comae detected in mid-March, lasting a
few days. Quasi-simultaneous spectral energy distributions are presented,
incorporating optical (AAVSO), and X-ray (Swift/RXTE) observations. We also
present the energy spectrum of the distant BL Lac (z=0.182) 1ES 1218+304 which
was detected by VERITAS during the 2006/2007 observing campaign. The energy
spectrum is discussed in the context of different models of absorption from the
diffuse extragalactic background radiation. We present multiwavelength
observations of the blazar Markarian 421 (z=0.03), including a strong flare
initially detected by the Whipple 10m gamma-ray telescope. Finally we present a
broadband spectral energy distribution for 1ES 2344+514 (z=0.044) which is
successfully fit using a one zone synchrotron self-Compton model.
