    "abstract": "Records of geomagnetic measurements have been analyzed looking for evidences\nof possible precursors for magnetic storms. With this objective, the main\nmagnetic storms in the period 1998-2002 have been located in Dst index record.\nPeriods immediately before storms and periods well before them were studied by\napplying a method recently introduced in the literature. Statistical properties\nof both types of periods have been compared. One of the compared quantities was\nthe slope of the power laws that have been found for some relevant\ndistributions. A systematic deviation between slope distributions was found.\nThis might be the fingerprint of a non self-organized component in records.\nThere has also been found a correlation between slope values and the\ncorresponding storm intensities, which could serve as a probabilistic approach\nto magnetic storms forecasting. Data is from the low latitude Vassouras\nMagnetic Observatory.",
