Analyzing the Influence of Saint Patrick’s Day Geomagnetic Storm on the Maximum Usable Frequency (MUF) in the Brazilian Equatorial and Low-Latitude Ionosphere

Atmosphere
The variation in the maximum usable frequency (MUF) during geomagnetic disturbances is a key parameter for high-frequency (HF) radio communications. This study investigates MUF variability and related ionospheric parameters during the first geomagnetic ...

Evidence and Causes of an Unusual Super Plasma Bubble Occurrence During Weak Geomagnetic Conditions Over Europe

Space Weather
Using data from a cluster of ground‐based global navigation satellite system, we observed spatially extended enhanced ROTI over the European longitudes during a weak geomagnetic storm (Dst ≈ −50 nT) on 4 November 2023.
