AA7FV rises in moderate geomagnetic disturbance.

A peak Kp of around 5 overnight, coupled with plenty of disturbances in the preceding day or two, brought a nice enhancement of AA7FV's 2W, 14MHz signal from his large rhombic, aimed at Europe.

I was quite surprised at the short period of reception for AA7FV on August 28th, which came to an abrupt end.  When I checked the entire reception record for that station, it was confirmed that he would disappear for everyone in the UK about 21-22UT each recent day, under quiet geomagnetic conditions.

But, with a bit of energy pumped into the ionosphere by the past 24 hours of HSS activity, AA7FV's pattern changes dramatically, to be heard throughout the night, until dawn here:
