Tales from the southern hemisphere

A very welcome WSPRer has recently appeared on a regular basis - CP6EE - from Bolivia.  Welcome, because there are precious few WSPR stations anywhere in the southern hemisphere.  Even the former British colonies like ZL, VK and ZS and their ex-pat operators now have very few WSPR stations.

Both CP6EE and DP0GVN saw increases in signal levels as a small disturbance of the geomagnetic field passed around the local magnetic midnight period here last night.  Note the sharp spike in Z component direction at the centre of the plot.

CP6EE's received signal here responded to this disturbance, rising from low levels at 21:00UT and peaking at 21:20UT.  The signal continues to be stronger than before the disturbance for a long time after it occurs, so the increased signal has nothing to do with the greyline at either point on the globe:

DP0GVN, receiving my 1W signal, also saw a smaller level peak, occurring at 22:00UT:
