    "abstract": "We study scaling in fluctuations of the geomagnetic indices (AE, AU, and AL)\nthat provide a measure of magnetospheric activity and of the epsilon parameter\nwhich is a measure of the solar wind driver. Generalized structure function\n(GSF) analysis shows that fluctuations exhibit self-similar scaling up to about\n1 hour for the AU index and about 2 hours for AL, AE and epsilon when the most\nextreme fluctuations over 10 standard deviations are excluded. The scaling\nexponents of the GSF are found to be similar for the three AE indices, and to\ndiffer significantly from that of epsilon. This is corroborated by direct\ncomparison of their rescaled probability density functions.",
