The UCR large area solid-angle double scatter neutron telescope was flown to search for solar neutrons on 3 balloon flights on September 26, 1971, May 14, 1972, and September 19, 1972. The first two flights were launched from Palestine, Texas; the third was launched from Cape Girardeau, Missouri. The float altitude on each flight was at about 5 g/cm/sup 2/ residual atmosphere. Neutrons from 10 to 100 MeV were measured. No solar flares occurred during the flights. Upper limits to the quiet time solar neutron fluxes at the 95% confidence level are .00028, .00046, .00096 and .00090 neutrons/cm/sup 2/-s in the energy intervals of 10 to 30, 30 to 50, 50 to 100, and 10 to 100 MeV, respectively.
