  1. 1. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Viktor Olsson; [2023]
    Nyckelord :Local Geomagnetic Variations; Fluxgate Magnetometer; Space Weather; Solar Wind; Magnetic Measurements; Variometer; Solar Activity.; Lokala geomagnetiska variationer; Fluxgate-Magnetometer; Rymdväder; Solvinden; Magnetiska Mätningar; Variometer; Solaktivitet.;

    Sammanfattning : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. LÄS MER

  3. 2. A detailed study of auroral fragments

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Joshua Dreyer; [2019]
    Nyckelord :aurora; fragments; Svalbard; all-sky camera; MSP; ASK; EISCAT;

    Sammanfattning : Aurora occurs in various shapes, one of which is the hitherto unreported phenomenon of auroral fragments. For three periods of occurrence of these fragments their properties were studied in detail during this master’s thesis, using mainly ground-based instrumentation located near Longyearbyen on Svalbard, Norway.

  4. 3. Pc5 Detection in Geosynchronous Particle Data Using Artificial Neural Network

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Erik Lysell; [2011]
    Nyckelord :;

    Sammanfattning : Geomagnetic pulsations are magnetohydrodynamic (MHD) waves in Earth‘s magnetosphere that can be seen as variations in the magnetic and electric fields, but also in particle data. Artificial Neural Network’s (ANN’s) ability to recognize patterns have been used to find Pc5 pulsations in geosynchronous electron flux data from LANL satellites. LÄS MER
