We present an analytical description of neutrino oscillations in matter based on the Magnus expansion of the time evolution operator. This approach incorporates in a simple and, at the same time, accurate way the Earth matter effects on the flavor transition probabilities in a wide interval of the neutrino energies. As a concrete application, we examine the daily change in the observed flux of the electron neutrinos coming from the sun.
