Oceania/Americas Sporadic-E

Band/Frequency Colour Key  
Note: Maps are no longer showing digi-mode contacts 
Due to the low-signal nature of some of the new digi-modes, such as FT-4 and FT-8, the traditional calculations for the MUF becomes inaccurate. I am therefore not displaying these digi-mode contacts on the maps until further notice.

The map above is auto-refreshed every minute or so. It’s generated by the application LiveMUF by Dave Edwards, G7RAU. This application is available to licenced radio amateurs to produce their own propagation maps.

Coloured lines indicate sporadic-E propagation reported in the following frequency bands during the last 30 minute period:
Blue lines = 28 MHz
Yellow lines = 50 MHz
Orange lines = 70 MHz
Red lines = 144 MHz
No-lines visible = No propagation reported
White parallel lines crossing the map = day/night terminator
Yellow star = Sub-solar point

The data block in the bottom left corner includes the date and the start/end times for the 30 minute period of the current map in UTC.
