We have recently interpreted the source MAGIC J0616+225 as a result of delayed TeV emission of cosmic rays diffusing from IC 443 and interacting with a cloud in the foreground of the remnant. This model was used to make predictions for future observations, especially those to be made with the Fermi satellite. Just recently, AGILE, Fermi and Very Energetic Radiation Imaging Telescope Array System (VERITAS) have released new results of their observations of IC 443. In this paper, we compare them with the predictions of our model, exploring the GeV to TeV connection in this region of space. We use Fermi data to consider the possibility of constraining the cosmic ray diffusion features of the environment. We analyse the cosmic ray distributions, their interactions and a possible detection of the supernova remnant environment in the neutrino channel. © 2010 The Authors. Journal compilation © 2010 RAS.
