On February 15th around 23 UTC a few webcams in the eastern Alps possibly captured a very faint red aurora above the northern horizon for a short period (above the yellow-green colours of light pollution). Most likely it was not visible to the naked eye. https://t.co/Epgdsd5hl9 pic.twitter.com/enD2qi1ggh
