TEP (Trans-Equatorial Propagation)

Band/Frequency Colour Key

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 TEP propagation reported in the following frequency band during the last 15 minute period:

Red lines = 144 MHz
No-lines visible = No propagation reported
White parallel lines crossing the map = day/night terminator
Black “X” = Positions of the geomagnetic poles
Yellow star = Sub-solar point

When TEP propagation is present and reported on the 2m (144 MHz) band, red lines crossing the geomagnetic equator indicate contacts as reported by amateur radio operators. Contacts remain visible on the map for 15 minutes. Note that not all lines may be actual TEP signals.

The data block in the bottom left corner includes the date and the start/end times for the 15 minute period of the current map in UTC.
