Scintillations Occurrences• Recombination of electron density

• Equatorial Anomaly -> favorable to occur

• Geomagnetic Storms

• Earthquakes -> quick changes in geomagnetic field

Final Remarks

• Concentration of occurrence of ionospheric scintillation over the Equatorial Anomaly TAIL.

• It is hoped that the scintillations points follow the tail of the anomaly, but the distribution of stations CIGALA allows a dense analysis on part of region of Brazil.

It is just a begining...Search pattern among indices (TEC, ROT, ROTI, Kp, … )

Necessity to detecting Multipath combined with ISM
