Calculations of the intensity of interstellar helium atoms at earth orbit are made with a model which takes into account perturbation of the Maxwell-Boltzmann velocity distribution by solar gravity and photoionization loss. Seasonal sky maps are presented and assessments of the sensitivity of the intensity of atoms in the vicinity of the earth to the various parameters of the gas are given. author
