Sign Up to like & getrecommendations! Published in 2018 at "Solar Physics"
DOI: 10.1007/s11207-018-1376-4
Abstract: We present a study of two active region jets (AR jets) that are associated with two C-class X-ray flares. The recurrent, homologous jets originated from the northern periphery of a sunspot. We confirm flare-like temperatures… read more here.
