A vast coronal hole, measuring approximately 800,000 kilometers in diameter, emerged on the surface of the sun. The high -speed solar wind is being issued in this region and must achieve Earth On January 31. Space climate experts indicate that this phenomenon has the potential to cause lower conditions of geomagnetic storms, which could improve auroral exhibitions in high latitude regions. The opening of the magnetic field of the sun in this area allows charged particles to escape to space at speeds of more than 500 kilometers per second.
Solar wind forecasts and geomagnetic storm
As reported By Space.com, according to data from Spaceweather.com, the coronal hole should influence the earth’s magnetosphere, with minor geomagnetic surveillance (G1) issued by the oceanic and atmospheric national administration (Noaa). The classification system used by NOAA classifies geomagnetic storms of G1 (smaller) to G5 (extreme). While the expected storm is at the lower end of the scale, increased dawn activity can be observed in areas closer to the poles.
Impact on aurora visibility
Solar wind particles interact with the earth’s magnetic field, thrilling oxygen and nitrogen molecules in the atmosphere. This reaction produces vibrant auroras, commonly seen as the north and south lights. A stronger influx of these particles can lead to a more intense and widespread avil activity. While G1 storms usually have limited impact, fluctuations on spatial climatic conditions can lead to variations in visibility.
Uncertainty in the prediction of space time
Although geomagnetic disorders have been foreseen, the spatial climate remains difficult to predict with absolute certainty. Some geomagnetic storm clocks result in minimal impact, while others produce unexpected peaks on avil activity. Those interested in tracking real -time spatial climatic conditions can use applications such as “My Aurora forecast and alerts” and “Spatial climate Live “for updated information about the visibility of aurora and solar activity tendencies.
