to observers on the ground, from green (the most common) to purple to red.

The first image (top) shows ribbons of light that shimmered over the Denmark Strait and Iceland at 04:45 Universal Time (4:45 a.m. local time in Reykjavík). The second image shows the view farther west, where the lights danced above the ********* provinces of Québec and Newfoundland and Labrador at about 06:30 Universal Time (1:30 a.m. local time in Montreal).

—the lowest level on a scale that goes up to G5—such storms typically make the aurora visible at high latitudes. G1 storms can also cause slight disruptions, including weak fluctuations in power grids and minor impacts on satellite operations.

from the Poker Flat Research Range near Fairbanks, Alaska, to study the electrical environment of an aurora. The GNEISS (Geophysical Non-Equilibrium Ionospheric System Science) mission’s two sounding rockets gathered data that will help scientists create a 3D reconstruction of the electrical currents flowing from the northern lights. Combined with observations from the ground and
