•	Physics governing MI coupling changes with spatial and temporal scale size. Space-borne imagery undersamples the true variability in the ionospheric response.
	•	Conjugate space-borne and ground-based imagery used to established the quantitative relationship between auroral variability and photometrically-derived conductance.
