Sažetak

Cutting-edge observations with the 1.6-meter telescope at Big Bear Solar Observatory (BBSO) in California have
taken research into the activity of the Sun to new levels of understanding of the structure and evolution of the
solar atmosphere at high-resolution spatial and temporal scales. On August 7, 2013 the NST observed active region
NOAA 11810 in photospheric and chromospheric wavelengths. The observations were performed as part of a program
conducted jointly with NASA's Interface Region Imaging Spectrograph (IRIS) mission, Solar Dynamics Observatory (SDO)
and Hinode satellite. These observations provided a unique view on the emergence of a buoyant small-scale magnetic-flux
rope in the solar photosphere. The event is accompanied by response of the solar atmosphere once the newly emerged field
interacts with the pre-existing overlying one. The reconnection process that takes place in the region produces jet
emission and high-temperature points in the chromosphere and corona.
