Description
We present here the results of the analysis of the gamma-ray blazar, 1ES 1215+303, over a 10-year period, from 2008 to 2017, measured at high energies (HE; 200 MeV < E < 100 GeV) by the Fermi Large Area Telescope (LAT) and at very high energies (VHE; E > 100 GeV) by Fermi-LAT and VERITAS. This is the longest temporal study of this high-frequency-peaked BL Lac object at gamma-ray energies. The spectrum follows a log-parabola over this time period, and its HE and VHE spectra are well-connected. Its flux is sufficiently strong at HE to allow us to bin the Fermi-LAT data in 3-day intervals, enabling us to investigate the time evolution of the flux in unprecedented detail. Several flaring episodes were detected and evidence for an overall trend of increasing flux over the span of the 10 years was observed. These light curves, in addition to the spectra, will be presented. This unique data set will help us to advance our understanding of the underlying physical processes in blazar jets.
