somebody posted a thread yesterday asking why on this. [link to www.swpc.noaa.gov
I don't know why, as this seem related to x ray flares and that is sorta of quiet right now, so I don't understand why the increased absorption in the polar areas. today's x ray flux [link to www.swpc.noaa.gov
] the proton flux is a bit elevated too [link to www.swpc.noaa.gov
] which would be reflected in the first link above also, but why the proton flux is higher, I don't know. flux is NOT the numbers, its the energy of vibration of the protons, as is the x ray flux and other fluxes.
the bz was negative for a long time but I have seen it such without this above.
the electron flux is not high at all. [link to www.swpc.noaa.gov
the haarp TEC is HIGH and snce Haarp is located near the north polar region, I would assume this is somehow related to the global drap, first link above. [link to www.haarp.alaska.edu
so as to WHY the polar regions are active right now, I don't know. but i am curious about it.
