Abstract :
In this paper, a new method is applied to calculate the magnetic energies of active regions and sunspots in satellites images. Digital images from the Solar & Heliospheric Observatory (SOHO) satellite are used in this study. The magnetic energies are calculated using the Ising model, which has been modified for our application. The new algorithm is integrated with our existing ASAP system (Automate Solar Activity Prediction). Extensive testing was carried out and the promising results are obtained that will aid in enhancing the accuracy of our automated real-time solar prediction system are presented.
