A solar storm in November 2025 caused GPS errors of more than 10 meters over the US

TechnologyInternationalEl ConfidencialOct 29, 2026, 1:00 AM35 s readAI summary

A study led by space physicist Endawoke Yizengaw of The Aerospace Corporation, published in Geophysical Research Letters, reconstructed a solar storm in November 2025 that disturbed the ionosphere over North America. Researchers detected a band of high electron density that crossed the ionosphere from east to west, with sharp changes at its edges that generated irregularities and amplitude scintillation in navigation signals. In some areas the horizontal GPS error exceeded 10 meters.

Emcali selected the consortium that will modernize more than 100,000 streetlights in Cali with LED technology
Cali will have 100% of its public lighting with LED technology through a COP 450,000 million project that includes modernizing 101,037 lights and installing 3,945 new points, with an 18-month execution period and operation and maintenance of up to 20 years. Emcali reported that three bidders submitted proposals and that works would begin with resources from the strategic partner, with disbursements only against effective execution. The model includes telemanagement, at an estimated COP 121,000 million, and would not require new debt for the city.
