The only anomalous propagation of my 100mW at 14MHz was to TF1A and EA8BFK, stations lying at 335 and 212 degrees from me as a magnetic heading.
TF1A was hearing until 01:00UT at -17dB SNR, EA8BFK also until 01:00UT, at -12dB SNR.
Interestingly, TF4M, who lies 189km NNW from TF1A, did not hear me at all after 21:42UT, despite having an extremely good station and location. Typically, around my local magnetic midnight, TF4M is just underneath or slightly to the north of the inner edge of the auroral oval, whereas TF1A is typically around the middle of the oval. The longer path through the oval is likely the explanation for my signal failing to get through to TF4M.
It's extremely difficult to correlate the cause of this roughly 90 minute extension in propagation to any of the field components, across any of the northern hemisphere magnetometers.
TF1A kept hearing my 100mW throughout the very disturbed conditions. More typically, anomalous spots tend to appear around the point where the field is restoring to quiet levels, and this is what was seen with EA8BFK last night.
