On 8 May 2024, the solar active region AR13664 started releasing a series of intense flares. Those class X released between 9 and 11 2024 gave rise to chain fast Coronal Mass Ejections (CMEs) that proved be geoeffective. The Storm Sudden Commencement (SSC) resulting geomagnetic storm was registered on 10 it is, date, strongest event since November 2003. storm, named hereafter Mother’s Day peaked with Dst –412 nT stands out as “standard candle” affecting modern era technologies prone Space...
Abstract The study of the preparation phase large earthquakes is essential to understand physical processes involved, and potentially useful also develop a future reliable short-term warning system. Here we analyse electron density magnetic field data measured by Swarm three-satellite constellation for 4.7 years, look possible in-situ ionospheric precursors interactions between lithosphere above atmosphere ionosphere, in what called Lithosphere-Atmosphere-Ionosphere Coupling (LAIC). We...
Abstract The geomagnetic storm that occurred on 25 August 2018, is, during the minimum of solar cycle 24, is currently strongest ever probed by first China Seismo‐Electromagnetic Satellite (CSES‐01). By integrating in situ measurements provided CSES‐01 (orbiting at altitude 507 km) and Swarm A satellite ca., 460 with ground‐based observations (ionosondes, magnetometers, Global Navigation System receivers), we investigate ionospheric response lower‐ mid‐latitudes over Brazil. Specifically,...
Nowadays, the possibility that medium-large earthquakes could produce some electromagnetic ionospheric disturbances during their preparatory phase is controversial in scientific community. Some previous works using satellite data from DEMETER, Swarm and, recently, CSES provided several pieces of evidence supporting existence such precursory phenomena terms single case studies and statical analyses. In this work, we applied a Worldwide Statistical Correlation approach to M5.5+ shallow first 8...
We analyse Swarm satellite magnetic field and electron density data one month before after 12 strong earthquakes that have occurred in the first 2.5 years of mission lifetime Mediterranean region (magnitude M6.1+) or rest world (M6.7+). The search for anomalies was limited to area centred at each earthquake epicentre bounded by a circle scales with magnitude according Dobrovolsky’s radius. define statistically terms specific thresholds respect same statistical quantity along whole residual...
On 20 December 2021, after six quiet years, the Hunga Tonga–Hunga Ha’apai volcano erupted abruptly. Then, on 15 January 2022, largest eruption produced a plume well registered from satellites and destroyed volcanic cone previously formed in 2015, connecting two islands. We applied multi-parametric multi-layer study to investigate all possible pre-eruption signals effects of this activity lithosphere, atmosphere, ionosphere. focused our attention on: (a) seismological features considering...
The 15 January 2022 eruption of the Hunga volcano provides a unique opportunity to study reaction ionosphere large explosive events. In particular, this event allows us global propagation travelling ionospheric disturbances (TIDs) using various instruments. We focus on detecting caused by over Europe, where dense networks both ionosondes and GNSS receivers are available. This took place day geomagnetic storm. show how data from different instruments observatories can be combined distinguish...
Abstract In early 2024 May, the solar active region AR 13664 released a series of X-class flares and multiple coronal mass ejections (CMEs) that resulted in strongest geomagnetic storm last 20 yr. This study aims at improving our understanding magnetic connectivity between Earth corona by reconstructing footpoint on surface during this superstorm. A Monte Carlo simulation was applied to model random walk interplanetary field lines due low-frequency turbulence wind. uses local diffusion...
During September 2014, intense solar activity led to a number of coronal mass ejections (CMEs) propagating in the heliosphere. The strong perturbation interplanetary magnetic field and remarkable enhancements energetic particle fluxes accelerated by shock waves associated with CMEs affected environments inner planets Solar System. Taking advantage relatively favorable position terms angular distance among Mercury, Earth, Mars, our purpose is observe evolution impact events, providing an...

Numerous forecasting now-casting modeling efforts resulted a remarkable add-on to overall progress field, at both national international level. The Agency has participated several missions with science objectives Weather; indeed, an important field for scientific industrial communities interested...

Solar energetic particle (SEP) events are often associated with solar flares. Such particles propagate through the interplanetary medium, where significant levels of magnetic turbulence found. We study connection from Earth to corona in three dimensional turbulence. In numerical simulation, different and wind velocities can be used. Input simulation is web-based data sets, comparison made flare observations contained Goes catalogue for years 1996, 1997, 1998, following minimum. For this set,...
The Na exosphere of Mercury is characterized by the variability emission lines intensity and its distribution in time scales from less than one hour to seasonal variations. While faster variations, accounting for about 10–20% fluctuations are probably linked planetary response solar wind Interplanetary Magnetic Field variability, variations (up 80%) should be explained complex mechanisms involving different surface release processes, loss, source migrations exospheric atoms. Eventually, a...
