For the northern hemisphere, winter and the solar maximum (However weak) means if you want to see the northern lights NOW is the time! This amazing photo by Dene Miles really drives home the awe that these events inspire. You may sit out for hours or even nights and see nothing at all but when they erupt, especially when you hit that prime location where those curtains into space seem to hang overhead you quickly realize that the wait and the cold was well worth it. Sadly, Dene doesn’t put any information on her website that describes the photo so where it was taken and when is a mystery.
The Aurora Borealis (North) and Aurora Australis (South) are the result of collisions between gaseous particles in the Earth’s atmosphere and charged particles that are released from the Sun. Variations in color are due to the type of gas particles that are colliding. The most common auroral color, green or yellowish green, is produced by oxygen molecules located about 60 miles above the earth. Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to 200 miles. Nitrogen produces blue or purplish-red aurora. The lights of the Aurora generally extend from 80 km (50 mi) to as high as 640 km (400 mi) above the earth’s surface and are centered around Earths polar-regions.

Want to view the aurora yourself? Check out my very rudimentary Aurora Guide that I threw together earlier this year. There’s plenty of information and 20-ish links of interest so you can learn and research more. https://danspace77.com/aurora-guide/
