Title:
"IRIS observations and NLTE modeling of the chromospheric UV
compact brightenings"

Abstract:
We used new high-resolution UV spectroscopic observations obtained by the
Interface Region Imaging Spectrograph (IRIS) to derive models of compact
brightenings  (CF) observed in the new flux emergence area
in the AR NOAA 11850. The main aim of this work is to estimate the height
formation of these small brightenings observed in chromospheric lines and
relate them to the well known Ellerman Bombs (EBs) phenomena.
