DESCRIPTION:Speakers: Salvo Guglielmino (Istituto Nazionale di Astrofisica
  (INAF))\nRecent ultraviolet observations performed by the IRIS satellite 
 have shown the occurrence of small-scale eruptive phenomena\, characterize
 d by significant increase of the integrated line intensity (up to a factor
  of 100 in Si IV lines) and of the line width (up to ± 100 km s$^{-1}$)\,
  likely due to magnetic reconnection. Some of these events also exhibit co
 unterpart in all the SDO/AIA channels.\nWe report on a series of similar e
 vents observed during secondary flux emergence in an arch filament system 
 in active region NOAA 12585. We use high-resolution observations acquired 
 by SST/CRISP relevant to the photosphere and the chromosphere to character
 ize the magnetic field configuration and the phenomena occurring in the lo
 w atmosphere. IRIS and SDO/AIA observations reveal the atmospheric respons
 e and the presence of heating and plasma ejection activity in the upper at
 mosphere.\n\nhttps://meetings.aip.de/event/24/contributions/332/
