Manufacturing Aurorae

21 September 2021

A post at Tall Bloke's talk shop – https://tallbloke.wordpress.com/2021/09/20/earth-can-makes-its-own-auroras/ .. which is derived from https://spaceweatherarchive.com/2021/09/20/earth-can-makes-its-own-auroras/ … earth can manufacture its own auroras, we are told, without any input from the solar wind. Admittedly, they are somewhat dim, like a pea soup without the ham, but an aurora of sorts none the less. They represent a bit of energy input into the upper atmosphere – at night. They are dubbed, diffuse auroras, a fitting description – but perhaps one that requires a bit further research. See for example https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020JA028743 … and https://pwg.gsfc.nasa.gov/istp/polar/2000sept.html
