Northern Lights seen in Portugal after major solar storm struck Earth
The current storm, the most powerful observed “since 2003”, is producing Northern Lights in regions where they are not usually seen. It could cause disruptions to power grids and satellites.
Northern Lights return to paint the skies
A large solar storm has begun to hit Earth, producing northern lights visible across Europe, including in Portugal. It could cause power outages.
Major solar storm brings more northern lights to Portugal
A major solar storm began hitting Earth on Monday and could cause disruptions to power and satellite networks, US weather officials have warned – as well as producing aurora borealis The post Major solar storm brings more northern lights to Portugal appeared first on Portugal Resident.
Northern Lights recorded in Portugal after major solar storm hit Earth
Observers across parts of Portugal reported sightings of the Northern Lights following a powerful solar storm that sent charged particles towards Earth, causing geomagnetic disturbances and making auroras visible at unusually low latitudes.

They are expected to continue on Tuesday, but to weaken during the day.
Northern lights observed in Portugal after major solar storm hits Earth
Solar eruptions, known as coronal mass ejections, which can take several days to reach Earth, cause these events, producing the aurora borealis and aurora australis when they interact with Earth's magnetic field.
Solar storm produces aurora, may disrupt grids and satellites
US meteorological authorities report a major solar storm has begun hitting Earth and warn it could cause disruptions to power grids and satellite systems while producing northern lights visible as far south as Portugal. Authorities advise operators of critical infrastructure and satellite services to monitor space‑weather alerts and prepare for possible interference. Those relying on satellite communications, GPS‑sensitive services, or with critical power needs should follow official updates.
A solar storm occurs when the Sun ejects large bursts of charged particles and magnetic fields (for example, coronal mass ejections) that interact with Earth's magnetosphere, causing geomagnetic storms. These storms can disrupt satellites, GPS and radio communications, induce currents in power grids, and produce visible aurora far from the poles (including in Portugal during strong events); agencies such as NOAA use a G1–G5 scale to indicate storm severity and likely impacts.
