EUV observations of subflares and surges

EUV observations of two subflares and associated surges have been analyzed. At maximum brightness the emission measures and radiative outputs of the subflares were approximately 20% of the corresponding values for the active region. Multiple EUV surges were observed during and following each subflare, with surge material being ejected in a variety of directions, including toward a coronal bright point located outside of the active region. The total energy of the surges appears to be comparable to that radiated by the subflares, a few times 10²⁸ erg. As reported in previous studies of surges, we find that there was no significant emission from these features in spectral lines formed at temperatures T>10⁶K. The ejection of surges in several different directions and nearly simultaneous flaring of various areas of the active region suggest that the primary site of the subflares was magnetically connected to a variety of different areas in the active region and the surrounding quiet region.
