1. 1. Development of a model for ionospheric instabilities in the equatorial region

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Thea Lepage; [2023]
   Keywords : ;

   Abstract : This work is part of a bigger project on analyzing the ionospheric dynamics in the equatorial region using simulations. The main objective of this study is to determine and characterize the parameters needed to trigger instabilities and thus the formation of plasma bubbles. READ MORE

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

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Viktor Olsson; [2023]
   Keywords : 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.;

   Abstract : 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. READ MORE

4. 3. Investigation of inductive electric fields in Earth’s magnetotail using Magnetospheric Multiscale (MMS) multipoint measurements

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Marco Guerra; [2022]
   Keywords : ;

   Abstract : The mutual interaction between the solar wind and the geomagnetic field generates the magnetosphere. The magnetosphere is characterized by many large-scale perturbations, such as substorms, which are responsible for variations in the magnetic field. READ MORE

5. 4. Automatic Characterisation of Magnetic Indices with Artificial Intelligence

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Veronika Haberle; [2020]
   Keywords : artificial intelligence; magnetic indices; magnetically quiet periods; geomagnetic field;

   Abstract : The complex interactions between the Sun and Earth are referred to as Space Weather. Key parameters include magnetic indices which quantitatively describe geomagnetic activity by determining a baseline that removes the background magnetic field and allows quantification of the remaining activity during geomagnetic events.

6. 5. A detailed study of auroral fragments

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

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

   Abstract : 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.
