To estimate flight doses during the current month, use the most recent heliocentric potential available. Do not use a heliocentric potential more than two months removed from the month of interest. Flight doses for specific flight profiles normally change very little in a couple of months. We will provide these heliocentric potentials on request. The above data is based on ground level neutron measurements provided by Dr. Margaret D. Wilson working under the auspices of the Bartol Research Institute at the University of Delaware and Dr. Eduard Vashenyuk of the Apatity Cosmic Ray Station of the Polar Geophysical Institute, Russia.
