ABSTRACT/ TECHNICAL SUMMARY:
We intend to study, the large-scale organization of the solar magnetic flux
and time series of magnetograms with the use of neural networks. The results
from the studies will then be incorporated in a hybrid intelligent system
which predicts the space weather from solar magnetic field observations.
Along the study we also hope to obtain improved and deepened knowledge about
fundamental problems within solar physics.
The study will take advantage of the unique quality of the solar magnetic
field observations made by SOHO. The magnetograms are characterized by both
high spatial (full-disk (4") and 11'x11' field (1.25")) and high
temporal (every 96 minutes and every minute during 8-hour campaigns) resolution
and by not being influenced by the degrading effects of the Earth's atmosphere.
These factors are of vital importance for our studies.
