Far East on 6m

Even with my attenuator in, I was spotting a Japanese station on 6m FT8. At first, as it is very early in the season for this, which happens every year in late June/early July, I assumed this was a pirate. 

However, when I spotted a second one I began to believe this could be real. 

It is believed this propagation is linked to noctilucent clouds which form usually in June and July. With climate change these seem to be more common.
