In the past four days we have seen 3-4 Earth directed full halo coronal mass
ejections occur in association with a series of M and X class solar flares.
I expect to see severe geomagnetic storming at high latitudes and major
geomagnetic storming at mid latitudes commence in 6-12 hours. High and mid
latitude night time propagation paths on the MF AM broadcast band, 160, 120, 90
and 80/75 meters will be most impacted. Also high and mid latitude propagation
paths at day time on 10, 12, 15 and 17 meters will be most impacted.
