He went QRT at 06:04 UTC and in his QRT comments mentioned the "incredible skip" today. I heard him work stations in the US and Canada but also in Russia, Sweden, Siberia, Finland and more.
The OH2 said that he had "been chasing McMurdo for 30 years" - the RW9 (in Siberia) and him exchanged weather observations and determined it was officially colder in Siberia than at McMurdo - and every time it sounded like Jason has signed off he would pull another out of the pileup and they'd have a QSO.
A fun night in the DX world.
