Chromospheric plasma ejection above a pore

Bharti, L.; Sobha, B.; Quintero Noda, C. +2 more

We present high spatial resolution observations of short-lived transients, ribbons and jet-like events above a pore in Ca II H images where fine structure, like umbral dots, light bridges and penumbral microfilaments, is present in the underlying photosphere. We found that current layers are formed at the edges of the convective fine structure, du…
