2.71, 5.22 This is indicative of still another light emission process. It is again the oxygen atom that is responsible for this color. The latter process is the same driver of the aurora, making STEVE a special kind of aurora hybrid. However, the auroral electrons sometimes have enough energy to give them the punch to penetrate deeper than that into the atmosphere.

"Auroras have been seen in the atmospheres of all the gas giant planets, which is not surprising, since these planets all have robust magnetic fields," said Jeff Regester, an instructor of physics and astronomy at High Point University in North Carolina. Strong solar activity causes strong variations in the solar wind; byproducts of this space weather are therefore geomagnetic storms and aurora. Aurora is visible at mid-latitudes during the largest magnetic storms, but it is dominated by red colors. "One of the more challenging aspects of nightside aurorae involves the comparison of the aurora borealis with the aurora australis," said Steven Petrinec, a physicist at the aerospace company Lockheed Martin who specializes in magnetospheric and heliospheric physics.

Its diameter is about 30 Earth radii, and outside of the magnetosphere is the solar wind. However, the number of hours of darkness decreases (increases) rapidly near the spring (fall) equinox so this caveat must be considered for those traveling to see the aurora. The bottom edge of a green auroral curtain gets this purple color when auroral elec-trons are accelerated to very high energy (Figures 7-8). Check out this pastel aurora activity!
