Počela najveća solarna oluja u poslednjih 20 godina, polarna svetlost stiže i do nas
Snažna solarna aktivnost koju oslobađa naša zvezda kreće se ka Zemlji. Oluja je ranga četiri, što je svrstava među opasnije, pa naučnici upozoravaju na moguće prekide u satelitskoj komunikaciji i upitnu tačnost navigacionih sistema. Lepa vest je što se i u našim krajevima očekuje veća verovatnoća za uočavanje polarne svetlosti.
TL;DR
- A solar storm ranked S4, the highest in over 20 years, is heading towards Earth.
- Potential impacts include disruptions to satellite communication, navigation systems, and increased radiation risk for astronauts and airline passengers on polar routes.
- During the May 2024 storm, some John Deere customers experienced GPS disruptions, and power grid operators managed increased geomagnetic currents.
- Auroras (Northern and Southern Lights) are expected to be more visible, potentially as far south as Alabama and Northern California, and across parts of Europe and the mentioned region.
- Increased solar activity is caused by coronal mass ejections and solar flares, with the recent event triggered by an X-class flare.
- Auroras are created by charged particles interacting with atmospheric gases, and can be viewed with cameras if not visible to the naked eye.
- Further eruptions from the active sunspot region are possible in the coming week, with potential to cause more Earth-directed events.
