Spacecraft positioned on the Sun-Earth line at Lagrange Point L1 encountered a cloud of rapid protons expelled during the recent solar flare. At a distance of about 1.5 million kilometers, this point hosts telescopes monitoring solar activity. The images from these telescopes reveal the characteristic ‘snow’ effect-trails left by charged particles passing through optical components and striking the telescope detectors.

These phenomena occur only during very intense flares and usually precede high-level geomagnetic storms, up to G5. The most recent instances of such powerful events were recorded in October 2003 and May 2024, marked by large-scale disturbances in Earth’s magnetosphere. Experts now confirm that the stream of solar particles is moving toward our planet. However, preliminary analysis indicates that the burst center is offset by about 20 degrees relative to the Sun-Earth line. This provides grounds to suggest that the impact on Earth will be partially mitigated. Earlier, it was reported that today at 20:00, a plasma cloud from a previous X-class flare would reach Earth. Furthermore, today saw the strongest solar flare of the year on the Sun.
The National Oceanic and Atmospheric Administration (NOAA) has recently observed similar solar activities, highlighting their potential to disrupt satellite operations and communication systems. Although the current trajectory is somewhat favorable, vigilance is still paramount. Scientists stress the importance of ongoing monitoring as the solar cycle intensifies, bringing an increased likelihood of disruptive space weather events.
