That's why I always had a rig tuned to the 6M SSB calling frequency, that's where openings usually start. Please pardon my bragging rights being I'm a DX magnet and have worked every propagation mode on 6, no lie. Here's my best DX on the magic band, if I hazard a guess it was rare F2 entirely possible at the peak of The Millennium Cycle. Go for it guys, since E is caused by UV independent of sunspot activity it can happen any day, but best in summer so watch the UV index in WX reports.
