aurora

<p>This comprehensive dataset combines all-sky auroral observations with high-resolution small-scale auroral data and is a resource for space weather research, magnetospheric studies and atmospheric science. The captured all-sky dataset classifies auroral displays into four different morphological types: arcs (smooth, curtain-like structures), folds (folded, undulating structures), radial corona (ray projections from a central point) and hotspots (locally bright regions).
