The sun 'explodes', threatening to disrupt global communications and satellites

Mexico has warned that increased solar activity could disrupt telecommunications, GPS and satellites, but said it would not affect human health.

The Mexican Space Meteorology Agency (Sciesmex) of the Geophysical Institute, National Autonomous University of Mexico (UNAM) on November 11 (local time) warned of the possibility of disruptions in telecommunications systems and satellite operations due to increased solar activity in recent days, but affirmed that this phenomenon does not pose a danger to human health.

Sciesmex's announcement said that in recent times, many strong solar flares, including one of the X5 class, have been recorded, along with coronal mass ejections (CMEs) heading towards Earth.

The agency predicts that CMEs will begin interacting with the space environment around Earth on November 11 and 12.

According to Sciesmex, this interaction could cause strong geomagnetic activity, similar to the magnetic storms that occurred in May and October 2024. However, this phenomenon does not pose a danger to human health but only affects technological systems.

Systems at risk include high frequency (HF) radio communications in aviation, maritime and operational services; satellite navigation systems (GPS/GNSS); telecommunications and Earth observation satellites; and large-scale power grids.

For GPS and GNSS systems, Sciesmex notes that strong solar activity can reduce the accuracy and synchronization of signals. Sciesmex affirms that the agency is maintaining constant monitoring of the situation and is closely coordinating with Mexico's National Civil Protection System to promptly respond to possible developments.
