Quiet conditions - a baseline analysis

The geomagnetic field has been extremely quiet over several days now, but things are set to change shortly.

 At the moment, the forecast is for a G1 - G2 storm commencing around October 20th, but with the potential to last for a couple of days.


I've made good use of the quiet prelude to this forthcoming disturbed period.  First, here is my baseline received 14MHz spots distance plot for October 12, showing how the 20m band dies in the overnight period:


Next, I've looked at my 14MHz reception of VK3QN and VK3MO.  Despite the near-total uniformity of the geomagnetic conditions over the days in question, there are still quite significant differences in the detail of how these two related stations (they are husband and wife callsigns!) are received:

Received SNR(14MHz), on 12, 13 and 14 October 2020.

We'll see what interesting things happen during the coming days!
