Overnight 14MHz WSPR report.

Overnight WSPR receive-only campaign continues with the following results:


Moderately disturbed field to Kp~5 for a brief period led to another early 14MHz reception of VK3QN, the appearance of the signal coinciding with the field restoring from a southerly Z swing to quieter conditions between 01 and 02UT.  The peak in signal at 05UT was seen in previous disturbed days, but the expected long path is brief, sporadic and weak:

The signal from LY3LT was caught dropping dramatically as the first, very sharp disturbance occurred around 16UT (this could also simply be the transition to night conditions), then being lost from ~19:30UT until it reappears between ~23:30 and 02:30UT.  I think the signal would have ordinarily disappeared from around 16-17UT under quiet conditions, and the weak 'ripples' in the reappeared signals are in response to the magnetic field:

Meanwhile, the disturbance produced sensitive and strong enhancements of the signal from F1JSC, which are definitely in response to the magnetic field:


 DK7KA also showed a response to the field disturbances around the midnight period:
