Abstract

We report on observations of the blazar Mrk 421 with the VERITAS experiment during the month of February 2010 taken in conjunction with a Fermi-LAT-organized multi-wavelength campaign. On February 17, 2010 an unusually bright flare was measured in TeV γ-rays reaching a level of ∼8 Crab with variability timescales as fast as a few minutes. A total of ∼15 hours of VERITAS data were taken over the month of February 2010 with the flare comprising ∼5 of those hours. We show the TeV spectra for several epochs including the flare and discuss results on X-ray/GeV correlation studies.
