Distance vs. UTC plot of my 10m WSPR signal

I've attached a distance vs. UTC plot of my 500mW WSPR signal on 10m for a 24 hour period. Interesting how it shows how the band opens and closes to different geographic locations. My signal is unheard on 10m from 0200-1400, begins to be heard in both NA and EU at 1400, EU drops off by 1800, East Africa lingers and Oceania picks up and stays to 0200. Also interesting to note that I'm not being heard by anyone closer that 1600 miles.
