A solar prominence, ejected on July 23, reached Earth on July 26 at approximately 21:00 Moscow time, but did not cause significant geomagnetic disturbances. The plasma cloud, predicted earlier, only led to weak fluctuations in the magnetic field at the moment of impact, after which the geomagnetic index returned to a stable green zone.
Despite the fact that Earth was in the plasma cloud for almost two days, no active events were recorded. The main indicator of the prominence's presence was a long series of constant northern magnetic field, which suppresses geomagnetic activity. Unlike the southern field, which could have triggered a magnetic storm, the northern direction ensured the absence of serious consequences, despite the intensity of the ejection.
Currently, Earth is still in the plasma cloud, but is expected to exit it on July 28.
Earlier, www1.ru reported that the solar wind had intensified, and the probability of the aurora borealis in Central Russia had increased.
