The geomagnetic storm warning is released! Please pay attention in the next few days →

On March 24th, the National Space Weather Monitoring and Early Warning Center of China Meteorological Bureau (hereinafter referred to as "Space Weather Early Warning Center") gave an early warning of the possible geomagnetic activities on March 24th, 25th and 26th, indicating that geomagnetic storms or even geomagnetic storms may occur during this period. Experts in the field of satellite meteorology interpret the early warning, indicating that spacecraft and homing pigeons are sensitive to geomagnetic storms, and suggest relevant units and homing pigeon enthusiasts to deal with them; Aurora may appear during geomagnetic storms, and enthusiasts interested in observing aurora can be prepared.

The coronal mass ejection process was photographed by the coronal instrument carried by SOHO satellite.

According to the information released by the Space Weather Warning Center, geomagnetic activity may occur on March 24, 25 and 26, among which moderate geomagnetic storms or even geomagnetic storms may occur on March 25, and it is expected that geomagnetic activity will last until March 26. According to the information released by the Space Weather Warning Center, the location of the coronal mass ejection (CME) process is almost right on the earth, so the ejecta form a round surface when viewed from the earth. The solar material ejected by this kind of explosive activity is faster than the earth and has high coverage, which may cause strong geomagnetic activity.

Cao Jing, an expert in scientific communication in the field of satellite meteorology in China and a senior engineer, said that geomagnetic storm is a violent disturbance phenomenon of the earth’s magnetic field caused by the "losing temper" of the sun, and spacecraft and homing pigeons are more sensitive to geomagnetic storm. During the geomagnetic storm or geomagnetic storm; the orbit for low-orbit spacecraft; including the space station; may drop uncontrollably; and the navigation error for satellites may increase. There have been geomagnetic storms encountered during satellite launch abroad that caused huge losses. Aviation flight has double risks of poor communication and trans-polar radiation; Carrier pigeons may get lost. During geomagnetic storms or geomagnetic storms, the earth may observe aurora.

Cao Jing suggested that pigeon lovers should not release homing pigeons during the geomagnetic storm warning period, so as to avoid the pigeons from "finding the north" and returning home. Friends who like to watch the aurora, pay close attention to the information released by the National Space Weather Monitoring and Early Warning Center of China Meteorological Bureau, and choose the right place to observe the aurora. Judging from the reply of the Space Weather Warning Center to netizens at noon on March 24th, it is not only the traditional "Arctic" Mohe area in China, but also most areas in northern China can try to observe.
