The National Autonomous University of Mexico (UNAM) warns about the possibility of a second geomagnetic storm which could last for the next few hours, which could trigger a new northern lights show in Mexico.
According to the report issued by the Mexican Space Weather Service (SCIESMEX) of the Institute of Geophysics of the UNAM issued yesterday, the recent geomagnetic storm (on May 10), which had a duration of more than 39 hoursis in the recovery phase, marking a gradual decrease in its intensity.
Mexico’s regional geomagnetic indices (kmex) have shown stability for more than 9 hours, signaling the end of the event.
Second geomagnetic storm will be more intense and lasting
However, the possibility remains that another solar storm impacts the earth’s atmosphere in the next few hours, which could revive geomagnetic conditions and prolong their duration.
The active region AR3664, responsible for the previous geomagnetic storm, is moving away from the solar limb, suggesting that future solar storms could have mitigated effects on our planet.
The northern lights, an extraordinary visual phenomenon caused by the interaction between the solar wind and the Earth’s magnetic field, illuminated the skies of Mexico with vibrant colors, being sighted from places such as Zacatecas, Sinaloa, Los Mochis, Ciudad Obregón and the coast of Yucatán.
This natural spectacle has transcended borders, with reports of sightings from the United States, Spain, Great Britain, Sweden, Australia and other countries.
Possible effects of the Second Geomagnetic Storm
According to the Space Weather Prediction Center (NOAA), with information from the first geomagnetic storm, the second event—which would occur during the following hours, with greater duration and intensity—would cause communication failures in HF high frequency radio bands.
As well as clouds of solar material (Coronal Mass Ejections) that would spread in the direction of Earth and are expected to affect the planet’s environment between today and tomorrow.
The UNAM added that Coronal Mass Ejections could cause global disturbances of the Earth’s magnetic field and affect satellites, telecommunications, global positioning systems, air navigation and electrical energy generation and transmission networks.
SCIESMEX will continue to closely monitor the situation and provide timely information to the National Civil Protection System to manage any possible impact.
