Multiwavelength imaging overview of the October 23, 2003, event at two different times. In both panels, the TRACE 195 Å image is plotted as a green background, with gray contours representing flare ribbons derived from pre-flare subtracted GONG intensity images. Red contours indicate RHESSI HXR images, while blue contours show RHESSI γ-ray images. The left panel depicts a time near the impulsive phase peak, and the right panel illustrates a time during the decaying impulsive phase. The time integration intervals for the RHESSI γ-ray images have been adjusted based on the contribution of the different flare phases to the neutron-capture line (see Sect. 3 for details).
