As a result of high-energy electrons crashing into oxygen atoms at altitudes above 200 miles, red auroras are exceptionally beautiful.
Red light's larger wavelength enables it to go further and is frequently visible at the bottom borders of an aurora.
Due to its reliance on accidents at higher altitudes, the red color is less frequent than green.
Active displays produce an unmatched natural light show as the red dances above the green.
Although a solar storm was expected on September 24, the intensity of the effect exceeded predictions.
A strong geomagnetic storm caused by the Sun's flare lit up the skies over Scotland, Iceland, and the Netherlands in brilliant green and red.
This year has been especially exciting for aurora hunters, with numerous astounding displays of the northern lights extending unusually far south.
The most recent red aurora saw was in February, and a fairly active solar cycle is thought to be responsible for the frequent occurrence of such phenomena.
