The effects of the May 2024 Mother’s Day superstorm over the Mediterranean sector: from data to public communication Open
On 8 May 2024, the solar active region AR13664 started releasing a series of intense solar flares. Those of class X released between 9 and 11 May 2024 gave rise to a chain of fast Coronal Mass Ejections (CMEs) that proved to be geoeffectiv…

Space Weather Effects On Plasmasphere, Ionosphere and Thermosphere Systems during November 2021 Geomagnetic Storm, as probed in the Northern Hemisphere Open
On 4 November 2021 it was detected the most intense geomagnetic storm that occurred so far during the rising phase of solar cycle 25 (Kp=8-). This work summarizes the state of the solar wind before and during the geomagnetic storm, the res…

Space Weather Effects Observed in the Northern Hemisphere during November 2021 Geomagnetic Storm: The Impacts on Plasmasphere, Ionosphere and Thermosphere Systems Open
On 3 November 2021, an interplanetary coronal mass ejection impacted the Earth’s magnetosphere leading to a relevant geomagnetic storm (Kp = 8-), the most intense event that occurred so far during the rising phase of solar cycle 25. This w…

On the validation of K-index values at Italian geomagnetic observatories Open
The local K index and the consequent global Kp index are well-established 3 h range indices used to characterize geomagnetic activity. The K index is one of the parameters that INTERMAGNET observatories can provide, and it has been widely …

The longitudinal polar cusp displacement from geomagnetic measurements in Antarctica Open
We used ULF geomagnetic field measurements in the Pc5 frequency range (1.7-7 mHz) attwo Antarctic stations to statistically investigate the longitudinal location of the polar cusp.The two stations are located at the same geomagnetic latitu…

Airborne Radio Echo Sounding (RES) measures on Alpine Glaciers to evaluate ice thickness and bedrock geometry: preliminary results from pilot tests performed in the Ortles Cevedale Group (Italian Alps). Open
Radar exploration supports glaciological studies playing several roles in ice exploration such as determining ice thickness and volume, describing ice and snow internal layering and characterizing crevassed areas. The method, widely used w…

A study of geomagnetic field variations along the 80° S geomagnetic parallel Open
The availability of measurements of the geomagnetic field variations in Antarctica at three sites along the 80° S geomagnetic parallel, separated by approximately 1 h in magnetic local time, allows us to study the longitudinal dependence o…

Low frequency geomagnetic field variations at Dome C (Antarctica) Open
We conduct an analysis of the geomagnetic field variations recorded at the new Antarctic station Dome C, lo-cated very close to the geomagnetic pole, which has been op-erating for approximately one month during the 1999–2000 campaign. We a…
