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). There, the particles interact with gases in our atmosphere resulting in beautiful displays of light in the sky. The outstanding brightness and dominance of high altitude red oxygen emissions indicate that during such storms the magnetosphere has very large currents flowing, while the auroral acceleration only produces low energy electrons. Follow the team's Twitter account to see the latest UK alerts. Original Price $85.99 These FPI wind observations only give the component of the wind velocity along the line of sight, the component toward or away from the observing station.

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.

WebThe aurora's characteristic wavy patterns and 'curtains' of light are caused by the lines of force in the Earths magnetic field.
