It's a good thing the shields are holding up as the intensity of pressure looks very strong.
D-layer absorption looks intense in the South Polar region:

Anybody know of an Antarctic Aurora Australis cam?
Quoting: Hugh M Eye well thats just cause the winds have not went south yet ^^
i guess i never get the "shield" phrase being used
the winds go south with a negative Bz, we get a storm
they stay north with a positive Bz, we dont
the winds need to go south to connect with earths magnetic field
its all just magnetic connection, combined with how fast the winds are and how much mater (density) they carry with them (this is the pressure)
when we get a lot of pressuere, combined with the winds going south (negative) then we get a geomagnetic storm
the stronger the pressure, and the more south the Bz goes, the stronger the geomagnetic storm
just throwing this in here for any new comers :)
