I am carefully checking 10m WSPR this evening to see if the long-path to Australia (over the Pacific) opens, especially seeing how the band has been open to the USA and Canada for hours now. My WSPR is running overnight, but if the band is to be open long-path I suspect it will be very soon. As I write this it is 2207z.
UPDATE 2217z: All quiet on 10m with my last USA spot at 2126z, nearly an hour ago. Being a band of surprises, anything can happen!
