This yielded plenty of spots throughout the night from a handful of European stations, with one appearance by HZ1AM (23:32UT, -25dB from 200mW), and one from W1AIU (23:46UT, -26dB from 5W).

The W1 spot is interesting, and certainly anomalous.  Whilst the field had yet to fully restore to quieter conditions, the spot did tend to coincide with the restoration phase - a common finding here.

The other interesting variation to follow was that in the signal from Cambridge, UK station, G0CCL, showing beautiful peaks at (UT) midday and midnight, the midnight peak being a product of the disturbed conditions (a small number of 1W signals, sent occasionally by G0CCL, have been removed from the plot):

This is very different from a typical quiet day:
