A plastic scintillator counter with anticoincidence screen has flown in four balloon flights at a floating altitude variable between 4 and 5 rob, during night to day, day-time and night-time flights. The analysis and comparison of the day-time and night-time parts of the flights has given for the co

The upperlirnit on the solar neutron flux from 1-20 MeV has been measured, by a neutron detector on the OGO-6 satel!ite, to be less than 5 :-< 10 -z n cm -2 s -1 at the 95% confidence level for several flares including two flares of importance 3B and a solar proton event of importance 3B. The measur
Near solar maximum, hard X-ray microflares with peak 20 keV fluxes of > 10-2 (cm 2 s keV)-1, more than ten times smaller than for typical flares and subflares, can occur at the rate of about once every five minutes. We report here on a search for hard X-ray microflares made on a long duration balloo
