 What infos ares displayed?

The datas are provide from the lasts 250 dx spots.

- the number of spots on each band

- a bargraph relative to the umount of spots for each band

- if the bar is bleue, that's mean that the activity on the band is normal or less.

- if the bar is yellow, the activity of the band is above the normal.

- derivated rate of the dx spots (average/hour).

- some informations about the sun like SFI and SSN .

- the 4 lasts dx spots

How "normal" band activity is estimated?

For each band a statistic spot/mn indice was estimated from more than 3 millions of dxspots. This amount of spots were collected on the cluster network other the pasts 3 years.

By this way, the actual activity of a band is compare with the "normal" activity estimated earlier. Some weighting have to be done, because of the time dependent activity of each band (ie: 80m is more active during the night than in the daylight).
