A powerful solar flare was observed beyond the southeastern limb of the Sun. Although its intensity reached M3,3, it was probably stronger because the source was not yet visible.
Sun Reveals Its Hand: Powerful Flare from Star's Far Side Signals Imminent Arrival of Giant Active Region

On January 12, 2026, shortly after 00:30 UTC, orbital detectors aboard the GOES satellites registered a sudden, intense burst of X-ray radiation emanating from the Sun. This event reached its peak intensity by 00:31 UTC, officially classified as an M3.3-class solar flare. While this marked the first mid-range M-class event of the year, its true significance was far greater than the initial classification suggested. The origin point of this eruption was not on the face of the Sun visible from Earth, but rather directly behind the star's eastern limb—on the hidden, far side.
In the image, a coronal mass ejection is leaving the Sun after a powerful solar flare at the southeastern edge of the disk.
This observation provides rare and crucial intelligence. The majority of the high-energy radiation and plasma ejected during the flare was naturally obstructed by the bulk of the Sun itself. Nevertheless, a portion of the energy, radiating from the upper layers of the solar corona, managed to skirt the edge of the star and reach our instruments. Astronomers are in agreement: if the attenuated signal registered as an M3.3, the flare's actual power likely corresponds to the maximum X-class level. Furthermore, this is the second significant explosion detected in the same general area in a short timeframe; a comparable event was logged just four days earlier, on January 8, 2026.
The accumulated data paints an extraordinary picture. Currently, the largest active center observed this year is in the process of emerging from behind the solar horizon. This concentration of intense magnetic fields possesses the capability to unleash colossal flares and Coronal Mass Ejections (CMEs). The situation is unique because we effectively 'saw' its power before it came into direct view, much like hearing the thunder before the storm cloud crests the ridge line.
Analysis of the information gathered by space-based solar telescopes has enabled the creation of visual reconstructions of the event. These show the dynamic loops of superheated plasma—the telltale signs of magnetic field line reconnection following a massive ejection. Fortunately, this particular flare caused no direct impact on Earth, as the primary ejection trajectory was directed away from our planet.
However, the situation is rapidly evolving. Within the next 24 to 48 hours, this active region will become fully observable from Earth. Scientists will then be able to conduct initial assessments of its potential and forecast its possible influence on space weather over the coming weeks. This provides an unusual opportunity for proactive forecasting, highlighting how monitoring the 'unseen' portions of the Sun offers vital clues about our star's future behavior.
The fact that two powerful flares originated from this budding region so close together strongly suggests that the emerging active center is highly complex and potentially unstable. As it rotates into full view, space weather monitoring agencies will be on high alert. The energy signature detected from the far side serves as an early warning system, giving ground control teams a head start in preparing for potential geomagnetic disturbances once the region is fully facing Earth.
