Not an awful lot happening that was unusual overnight, with the field staying at Kp = 1. But I was interested to see 2E0XLG, who I think is new to WSPR and only 158km from me, appear as a remarkably constant ground wave signal from 0.2W output, throughout the darkness (blue vertical line = UT midnight):

The small positive deviation in signal strength at 21:36UT is correlated to (but not necessarily caused by) a field restoration from a modest southerly deviation at very high latitudes, as indicated by Svalbard magnetometers (line labelled 'bjn' (Bjørnøya, or Bear Island, 74.5 degrees north)):

This is very interesting to compare with G0CCL, running 5W, at just over twice the distance from me (353km), which seems to be undergoing very intermittent propagation via non-ground wave paths, as the upward curve of much more consistent signals around sunrise suggests:
