A forecast for a fairly major, G3 disturbance became reality last night, although the peak was fairly short lived:
It's always interesting to note what happens on the north-south circuit during these events. DP0GVN in Antarctica vanished at 10MHz with the onset of the disturbance, but at peak field deviation, yielded a single spot, only to vanish again until the advancing morning propagation.

The effect of the disturbance is also very clear when we plot all received distances of spots against time - a big gap develops for around three hours from around the midnight point. Indeed, it was only spots from TA4/G8SCU that kept things going at all in this gap, with a couple from SV1DAR, too, both running 5W:
