Abstract: | It is shown how the hard X-ray burst count rate and itse-folding ime can be used to estimate the minimum magnetic fieldBmin required in a flare magnetic reconnection site for the burst to be interpreted in terms of a thick target model. Application of the method to data from the Solar Maximum Mission (HXRBS) indicates absolute minimum fields well in excess of 100 G, and impossibly high values for some reconnection geometries. |
