Spectroscopic Diagnosis of a B-Class Flare and an Associated Filament Eruption
B. Suresh Babu, Pradeep Kayshap, Sharad C Tripathi
The flare ribbon and an associated filament eruption are diagnosed using O iv 1401.16 A, Si iv 1402.77 A, and Mg ii k 2796.35 A spectral lines provided by IRIS. The flare ribbons h…
