Three clouds from the Sun are hurtling toward Earth all at once.
Three plasma clouds ejected toward the planet are currently hurtling toward Earth. This is indicated by the latest observational data and predictive models.
A surge in solar activity will trigger magnetic storms this coming Friday.
The space weather forecast for the next 2–3 days has become reasonably clear. Calculations indicate that the plasma cloud ejected by the Sun yesterday midday will take nearly three days to travel to Earth, arriving on Friday morning. Upon impact, it will—as expected—trigger the full, traditional chain of space weather phenomena, ranging from geomagnetic storms to auroras.
A new solar eruption has hurled a cloud of plasma toward Earth.
The surge in solar activity that began yesterday evening continues to intensify rapidly. Over the past three hours, two additional strong flares—classified as M1.9 and M1.4—have occurred on the Sun, ranking second and third in intensity among all events of autumn 2026. These explosions ejected at least two sizable plasma clouds into space, both of which are moving toward Earth.
The largest surge in activity on the Sun in a month is being observed.
It appears that yet another attempt to rebound from a low point is currently underway on the Sun. The star—whose activity has been suppressed for about a month—unexpectedly began producing a series of flares yesterday evening; one of these, an M1.0-class flare occurring around 10:00 PM Moscow time, was the largest since September 5.
The second magnetic storm of autumn has ended.
The second magnetic storm of this autumn has occurred and concluded on Earth, arriving a day later than forecast. Only one such event had previously taken place during September and October: a weak G1-level storm recorded on September 8. As predicted, the current storm was caused by the impact of a medium-sized coronal hole; while this influence is still ongoing, the peak intensity has already passed.

A lull in solar activity continues, marked by periodic, unsuccessful attempts to rise from the minimum. Another such attempt is underway right now. A C8.6-class flare occurred this morning—the strongest since September 5, or in nearly a month. Additionally, fairly large active regions emerging from the far side are visible on the Sun's left limb, above the equator.
The impact of the coronal hole on Earth did not result in a magnetic storm.
The impact of the latest coronal hole on Earth—forecast for Thursday, September 24—proved to be relatively mild. As expected, the Kp geomagnetic activity index rose from values of 0–1 to around level 3; it even briefly crossed the Kp=4 threshold—indicating geomagnetic disturbance (yellow level)—during the middle of the day yesterday, but it never reached the threshold for a geomagnetic storm.
Space weather on September 22, 2026
Nothing significant has occurred on the Sun over the past few days; the star remains in a quiet state. The most notable event in the coming days will likely be the second magnetic storm of autumn, expected on September 24—this coming Thursday.
For the first time since 2021, not a single solar flare has occurred on the Sun over a four-day period.
Solar activity—to the dismay of some and the delight of others—continues to set new record lows. For the first time since December 2021, not a single solar flare of Class C or higher has been recorded on the star over a four-day period.
Solar activity has decreased threefold over the past two years.
Solar activity has dropped nearly threefold over the past 24 months, falling from a level of 216 units in August 2024 to 76 units this past August, 2026.
