Although 6m Es has been rather quiet, there was some TEP between Japan and Australia. TEP often allows stations across the magnetic equator to work each other at MUFs far above those expected. I think chordal-hop is involved. TEP between the Med area and southern Africa has even occurred at 2m!
In most recent years there has been 6m propagation between Japan and Australia. This mode may well account for some of the N-S propagation on 10m. It favours stations a bit nearer the equator. In the UK we need Es as well to get us into the area where there is TEP. Just occasionally it happens this far north.
