Dynamics of solar isolated features observed by the Atacama Large Millimeter/submillimeter Array (ALMA)

Four time series of solar images, observed by the Atacama Large Millimeter/submillimeter Array (ALMA) in December 2016 and in April 2017, were analysed. The datasets were recorded in bands 3 and 6 at 2.6-3.6 mm and 1.1-1.4 mm, respectively. This study focused on the tracking of isolated solar features, including both bright and dark small-scale structures. Tracing structures in image time series yields information about their lifetimes, velocities, and area variation with time at the two passbands. By using co-aligned ALMA images with those observed by the Solar Dynamics Observatory (SDO) is provided context of the large-scale structures at various layers of the solar atmosphere complementing the analysis of the tracked features.
