The detailed objectives for understanding the heating of the corona include, but are not limited to, the following:
1.2.1.1 Energy flux in the lower atmosphere1.2.1.2 Energy and mass flux in the corona.1.2.1.3 Contribution of flare-like events on all scales1.2.1.4 Observe and explore flare-like ‘heating events’ from the quiet corona1.2.1.5 Determine whether coronal heating is spatially localized or uniform, and time steady or transient or impulsive for a wide range of magnetic loops with different spatial scales.1.2.1.6 Resolve the geometry of fine elemental loop strands1.2.1.7 Detect and characterise waves in closed and open structures1.2.1.8 Investigate the role of small scale magnetic flux emergence in energizing the above laying layers1.2.1.9 Multi-temperature diagnostics of flaring coronal loops1.2.1.10 Heating in flaring loops vs heating in active regions
