The solar storm that began on Friday and led to days of auroras borealis in some regions of Mexico ended this Sunday, as reported by the Institute of Geophysics of the National Autonomous University of Mexico (UNAM).

The Mexico Space Weather Service (Sciesmex) of the institute reported in a statement that the severe geomagnetic storm lasted over 39 hours but is now in the recovery phase, characterized by a gradual decrease in its intensity.

“The regional geomagnetic indices of Mexico (kmex) have indicated undisturbed values for more than nine hours, so we can consider that the severe geomagnetic storm event has concluded,” affirmed the institution.

Geomagnetic conditions in the atmosphere of the northern hemisphere have been the most extreme recorded since October 2003, which allowed the aurora to be seen in places where it is very rare, according to the National Oceanic and Atmospheric Administration (NOAA) of the United States.

According to the World Meteorological Organization, the storm consists of a luminous phenomenon in the upper layers of the atmosphere with shapes like arcs, bands, or curtains, at an altitude of between 90 and 150 kilometers, due to the interaction between the solar wind and Earth’s magnetic field.

The UNAM Institute of Geophysics warned that “there is a possibility of another solar storm hitting Earth’s environment in the coming hours,” so “the geomagnetic storm condition could again increase in intensity and extend its duration for a few hours.”

However, it clarified that the active region AR3664, responsible for the solar storms that caused the geomagnetic storm on May 10, is approaching the solar limb.

“It is expected that the solar storms it may produce now will have lesser effects on Earth,” concluded the report.
