That depth of midwinter has arrived when 14MHz becomes an interesting hunting ground for unusual, transient propagation during the long hours of darkness.
Last evening, with only a very minor field disturbance, I received WSPR from R4ADW, based in Volgograd, running 0.2W. This is an extremely rare winter overnight spot, and one I don't think I've ever seen previously.
A cursory look at Z (vertical) component field puslations suggests there may be a link, notably as the pulsations weaken and almost vanish in the post 01:15UT period.
