Is this related to the solar storm? Why is it pink?

Oxygen at higher altitudes has a different emission frequency apparently (I've only ever seen the faintest green pulsing aurora IRL)

It's possible to tell what elements something is made of by determining the spectra coming off of it when it's excited: https://en.wikipedia.org/wiki/Atomic_spectroscopy

Barely visible in Northern Italy—no pink worth calling home about—but the sky is sensibly lighter than it usually is.

The one pointed 'nordest' from Monte Grappa seems to show some pink:

Tried looking for some webcams in the Cortina area but they seem to have a lot of clouds. Some of which appear to have a pink hue.
