Observations of active region plage with SUMER and Hinode have detected small concentrations of H_2 near the footpoints of X-ray microflares. The H_2 is excited by the O VI line at 1031.94 Å which, although not observed, must be brightening along with the observed transition region line (Si III 1113.24 Å). About one third of the strong transition region brightenings in the plage excited observable H_2 emission. Each of the H_2 events occur at a footpoint of a brightening X-ray loop. It is suggested that microflare energy dissipation in the loop footpoint heats and reduces the opacity of the chromosphere, so that O VI microflare emission is able to excite the H_2.
