Short summary
Short summary
Gravity and tilt time series acquired at Conrad Observatory (Austria) reflect gravity and deformation associated with short- and long-term environmental processes, revealing a complex water transport process after heavy rain and rapid snowmelt. Gravity residuals are sensitive to the Newtonian effect of water mass transport. Tilt residual anomalies capture strain–tilt coupling effects due to surface or subsurface deformation from precipitation or pressure changes in the adjacent fracture system.

INTERMAGNET (International Real-time Magnetic Observatory Network) is a global network of over 100 magnetic observatories, working with the International Association of Geomagnetism and Aeronomy (IAGA). Its one-minute measurement data undergo a strict two-stage review by expert teams, ensuring high accuracy and consistency. Verified data are published online and as DOI. This gives researchers and practitioners fast access to reliable data for science and practical applications.

Short summary
A new magnetic observatory has been established on La Réunion Island in the Indian Ocean. This isolated observatory serves to monitor the evolution of the magnetic field in that region. It is also useful for large-scale modelling of the core field and other contributions to the geomagnetic field. The vector magnetic field components are measured every second, transmitted every 5 min to the Institut de physique du globe de Paris, and made immediately available to users (see www.bcmt.fr).

Short summary
The amplitude of subionospheric very low-frequency (VLF) radio signals does not show a symmetrical behavior over the year, which would be expected from its dependency on the solar position. The VLF amplitude rather shows a distinctive sharp decrease around October, which is hence called the "October effect". This study is the first to systematically investigate this October effect, which shows a clear latitudinal dependency.

Short summary
We use computed tomography to reconstruct the three-dimensional distributions of the Hall and Pedersen conductivities of pulsating auroras, a key research target for understanding the magnetosphere–ionosphere coupling process. It is suggested that the high-energy electron precipitation associated with pulsating auroras may have a greater impact on the closure of field-aligned currents in the ionosphere than has been previously reported.

Short summary
The pulsating auroral generation mechanism has been investigated by observing precipitating electrons using rockets or satellites. However, it is difficult for such observations to distinguish temporal changes from spatial ones. In this study, we reconstructed the horizontal 2-D distribution of precipitating electrons using only auroral images. The 3-D aurora structure was also reconstructed. We found that there were both spatial and temporal changes in the precipitating electron energy.
