10m WSPR overnight

At some point my shack PC decided to close the WSPR programme, presumably to install updates, but I was pleased and surprised to see M0XDC (65km) was spotted in the early hours of the morning. Judging by the Doppler, I think this was aircraft reflection.  Although I'm unsure when the program stopped I turned the PC and WSPR program on again at around 0700z and checked time sync.
