This map has all modes including digital modes and skimmer reports. For an uncluttered map with mostly SSB and CW contact reports click here.
This map does not include any F2 propagation. Long distance Es on 6m are often mis-reported as F2 contacts.

Digital modes have now been re-enabled.
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 calculated MUF is also shown on the map at the mid-point square, where the assumed ionospheric refraction occurs.
When propagation is present and reported, coloured rectangles at the mid-points of the contact lines indicate the MUF in those squares in MHz as calculated by the Live MUF application for contacts during the last 30 minutes.
The square colouring is scaled between yellow and red (28 MHz to 200 MHz).
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.
