We present a graphical way for the period April 2003 up to May 2004, to compare the observations with our forecasts concerning different solar indices: 10cm flux, the A_p index and the flare probability index.

The 10 cm flux:

Every day we predict 3 values: a first one for the day itself (2003, 2004, 2005), a second one for the next day (2003, 2004, 2005) and the last values concerns two days ahead (2003, 2004, 2005).
The prediction for the first day is compared with the observed values and with a lineair fit calculated with 4 previous data.We labelled our prediction for the first day as successfull if the forecast was better then the linear fit through the previous data points (2003, 2004, 2005).

the geomagnetic A_p index:

Concerning the conditions on earth, we do a forecast about the disturbance of the geomagnetic field. One can the categories ranging from quiet to severe storm levels. Similar to the 10 cm flux, we do a prediction for the first day (2003, 2004, 2005), second (2003, 2004, 2005) and third (2003, 2004, 2005) day. Note that the measured Ap index is in fact an estimated index for which local data of several stations are used. The relative error for every month is also available (2003, 2004, 2005)

Reliability of C, M and X-flare forecast:

Each day we do a global forecast for the flare probability given by an interval of percentages. Here we present a way to control if we either 'over' or 'under'-casted the C, M or X-class flares to happen over the period from April 2003 until now. (See the graphs.)

Similar plots are made for the flare probility forecast per day, per group. (See the graphs.)
