On May 11th, according to China Weather Network, influenced by multiple coronal mass ejections, a moderate to strong geomagnetic storm may occur today, with geomagnetic activity expected to last until the 12th.
For aurora enthusiasts, the geomagnetic storm may bring along the mesmerizing aurora borealis.
During a geomagnetic storm, artificial satellites and space stations orbiting at around 400 kilometers altitude may experience a decrease in orbit height due to atmospheric drag, leading to increased positioning errors in satellite navigation systems.
Aircraft flying in the lower stratosphere region of the atmosphere face a dual risk of deteriorating communication conditions and polar radiation during geomagnetic storms. Changes in geomagnetic intensity and inclination can also pose challenges for animals like homing pigeons that rely on geomagnetic navigation.
In conclusion, individuals in these fields should remain vigilant for space weather information in the coming days.
It is important to note that although geomagnetic storms can have some impact on spacecraft operations, their effects on human health and daily life are minimal.
Similar to the extreme geomagnetic storm that occurred on March 25th this year, the location of the coronal mass ejection (CME) process in this case is relatively favorable for Earth. When viewed from Earth, the ejected material forms a circular shape, known as a "full halo."
These types of eruptive events eject solar material at high speeds and with high coverage relative to Earth, which may lead to relatively strong geomagnetic activity.
