Abstract
UNLABELLED Small-scale dynamic auroras have spatial scales of a few km or less, and temporal scales of a few seconds or less, which visualize the complex interplay among charged particles, Alfvén waves, and plasma instabilities working in the magnetosphere-ionosphere coupled regions. We summarize the observed properties of flickering auroras, vortex motions, and filamentary structures. We also summarize the development of fundamental theories, such as dispersive Alfvén waves (DAWs), plasma instabilities in the auroral acceleration region, ionospheric feedback instabilities (IFI), and the ionospheric Alfvén resonator (IAR). SUPPLEMENTARY INFORMATION The online version contains supplementary material available at 10.1007/s11214-021-00796-w.

Abstract
An all-sky camera, a ground imager used since the 1950's in the aeronomy and space physics studies, was refurbished with a modern control, digitization, and archiving system. Monochromatic and broadband digital images of airglow and aurora are continuously integrated and recorded by the low-cost unmanned system, which is located in northern Canada. Radiometric corrections applied to the data include noise subtraction, normalization to a flat-field response, and absolute calibration. The images are geometrically corrected with star positions and projected onto a geographic or geomagnetic coordinate system. An illustration of the application of corrected all-sky camera images to the study of auroral spirals is given.
