Overview of the GONG intensity observations of the October 28, 2003, flare. The leftmost panel shows the continuum intensity image of the region where the flare happened. From the second to the fifth panel, we show the time evolution (around the peak of the impulsive phase at 1 minute time resolution) of the pre-flare subtracted continuum intensity images. From the pre-flare subtracted images, we can clearly see the flare ribbons. The percent level of the maximum increase in WL emission due to the flare is 35% of the pre-flare intensity.
