Abstract

The location and size of a solar impulsive hard X-ray burst have been determined in one dimension to a considerable precision with a balloon-borne X-ray modulation collimator. The center of the X-ray source is on the line passing through the center of a big Hα flare region of 3 arc min. The size of the X-ray source is remarkably smaller and may be one arc min or less.
