Quiet, except for 9Z4FV

Overnight saw extremely quiet geomagnetic conditions over Europe and Scandinavia, but slight disturbances further to the west, as shown by this Z component plot from West Greenland:

This is the only location of field disturbance that correlates with the sudden reappearance of 9Z4FV for about an hour.  At the peak of the 9Z signal - which is a high output of 20W - two UK stations also appeared (one spot only each at 01:24 and 01:26UT for G8LIK and M3PMG, respectively), but nothing else at all between 00:14UT and 03:06UT:
