Transient dynamics and energy transfer from the photosphere to the low corona: initial results from a coordinated ALMA, DST, Hinode, IRIS, and SDO observation campaign

We present initial results from a coordinated observation campaign to study transient dynamics and energy transfer in the low solar atmosphere. The observations ran from approximately 2017-03-21 from 13UT to 19UT, and include data from Hinode, IRIS, DST, and ALMA. The target, a small, magnetically bipolar active area associated with a coronal bright point, was chosen for showing reasonable dynamics in the chromosphere (as dictated by AIA 304 data from the day prior), and being near disk center to better facilitate magnetic field measurement. The campaign was designed to capture the dynamics of the target with as rapid a timescale as possible for each instrument. Photospheric dynamics are available from broadband IBIS data and the HMI. New to this dataset, the chromospheric dynamics were observed in radio frequencies using ALMA (Band 3: 92-108GHz) at a 2s cadence. Additional chromospheric data are spectral H-alpha from the IBIS instrument at the DST, spectropolarimetic HeI 10830 from the FIRS instrument at the DST, and the medium linelist from IRIS; coronal data includes imaging from XRT and spectral data from EIS. In this first set of results, we discuss the frequency of transient brightenings observed in each set of imaging data and how the spatial distribution relates across each data channel and to the regions magnetic topology.
