Observations of Mrk 421 with VERITAS

Markarian 421, a BL Lacertae object, is a variable source and can flare to many times that of the Crab Nebula. This source is observed by VERITAS, the Very Energetic Radiation Imaging Telescope Array System, which consists of four imaging atmospheric Cherenkov telescopes and is located in southern Arizona. During the 2007/2008 observing season we observed the source for over 30 hours and report the statistical significance to be 235 standard deviations. We compare our results to other years of data and summarize the mechanisms which are thought to cause the gamma ray emission.
