Auroras Expected in Germany Due to Solar Activity
The sun is experiencing its highest activity in over two decades, leading to intense polar lights. A recent solar flare, combined with a coronal mass ejection, is projected to strike Earth, causing a category four geomagnetic storm. According to NOAA, this event could result in auroras visible as far south as Germany, particularly in the northern regions. Viewers are encouraged to watch for the lights after 8 p.m. in dark areas free from light pollution.
Solar Flares and Polar Lights
A significant geomagnetic storm is expected, sparked by a solar event in which plasma was ejected from the sun. These geomagnetic storms cause auroras, more commonly known as polar lights or northern lights. The aurora zone is expected to shift southward, giving those in Northern Germany a rare opportunity to witness this phenomenon. The NOAA has issued a warning for potential auroras on Thursday and Friday night.
Technical Impacts of Solar Activity
While polar lights are a beautiful spectacle, they may also affect technology. GPS systems could experience disruptions due to distortions in satellite signals caused by a highly energized ionosphere. Additionally, amateur radio operators often use auroras to establish long-distance communication during these events. However, the overall impact on power grids or satellites is minimal.
Best Practices for Viewing Auroras
For the best chance of seeing the auroras, find a location with minimal light pollution. Northern parts of Germany are most likely to witness the lights, especially on Thursday night. If the auroras are faint, cameras can capture them more easily than the naked eye. Observers should also be aware that clear skies are essential for good visibility.
Effects on Aviation and Communication
Aside from the visual beauty of auroras, they have measurable effects on technical systems. GPS systems, in particular, may become less accurate. Some flights in polar regions may have to adjust their routes to minimize radiation exposure. Amateur radio operators can also use the event to extend the range of their signals through aurora reflections.
