Flare arcade and ribbon plotted with respect to (x,y) = 515,–268 between 12:02:52 and 12:02:58 UT in the red wings (left) of the Ca II K, Hα, and Ca II 8542 Å lines, as well as in a COCOPLOT (right). Colored cross-sections mark representative examples of ribbon freckles (red), the leading edge of the flare ribbon (orange), a blueshifted up-flow region (blue), and the flare arcade (white). Top row: Red wing of Ca II K along with a COCOPLOT. Second row: The same, but for Hα. Third row: Same but for Ca II 8542 Å. Bottom row: Maps of the Ca II 8542 Å line of the total linear (left) and circular (right) polarization.
