BREAKING: Five M-class solar flares have exploded in the... "Earth strike zone" from the Sun over the last 21 hours, the strongest being a M6.9, and CMEs have been launched towards Earth. Solar storm impacts and geomagnetic storming are expected in a few days...show more

Earth was hit by multiple CMEs triggering a G3-... geomagnetic storm last night, and we're now being buffeted by fast solar wind. More Earth-directed solar storms are racing towards Earth and are expected to impact in <12 hours now. I expect G3-G4 geomagnetic conditions, get ready!show more

In the last 38 hours we've had 1.7 and... 1.1 X-flares from the Sun, earthquake activity off the coast of Japan (M6.8, M6.4, M6.0) has becoming worrying and looking like foreshock activity for a BIG earthquake (M8+), and we're now in a S1 radiation storm from the 2nd X-flare. Multiple solar storm impacts are expected over the next few days. Big linear planetary alignment occurs on the 20th with the Sun, Mercury, Moon, Earth, and Uranus with Pluto and Saturn+Neptune in harmonic aspects. Yikes...show more

BREAKING: A powerful G5 level geomagnetic solar storm is... striking Earth right now Authorities have alerted infrastructure operators to brace for power grid fluctuations, GPS disruptions and satellite communication failures One of the strongest solar storm ever recordedshow more

131A imagery of the Sun showing the C-class solar... flaring that's been active the last ~2 days now. It's looking very likely we'll see M-flares and potentially X-flares in the days ahead.show more

Double hit directly over the Americas with 6.7 and... 6.3 M-flares. A solar storm impact is also already in progress, through the geomagnetic activity from it has been relatively muted thus far (+Bz)...show more

1.7 X-Flare from Earth bullseye launched a CME towards... Earth, impact expected in 48-72 hours. G2 geomagnetic conditions or greater are most likelyshow more

A series of reoccurring coronal holes are starting their... rotation through Earth-center, and the trans-equatorial coronal hole will be geoeffective in ~5 days. Earth was in the high-speed solar wind from this coronal hole after a G2 geomagnetic storm for the M7.8 Philippines EQ.show more

The Sun has really woken up over the past... 48 hours, producing multiple solar flares (including an “X-class” event), across 4 different regions. Further large flares are likely in the coming days!show more

Aurora borealis was seen around the world last night... — all because of an extremely powerful solar flare On Sunday, the first major solar flare of the year occurred — an X1.95-class event. A cloud of charged particles reached Earth in less than 24 hours. On the night of January 19–20, the aurora was observed in Russia, Ukraine, Belarus, Western Europe, and North America. An extremely strong geomagnetic storm hit the planet. Geomagnetic activity nearly reached the maximum G5 level. Disruptions have been reported worldwide. Radio signals, satellite navigation, and other systems dependent on a stable magnetic field have been affected.show more

In a cosmic embrace the Sun has launched two... coronal mass ejections to each side of the Earth. Neither will hit the Earth, but the overall energy flux from our Sun outwards into the Solar System has been elevated the past few days, strengthening the electromagnetic field of the heliosphere as a whole, just in time for the Great Saturn-Neptune Conjunctionshow more

The Earth's magnetic field protects us not only from... solar flares but also from cosmic radiation. When the Sun enters a Grand Solar Minimum, its magnetic field weakens for a long period. This lets more cosmic radiation into the Solar System, and this directly impacts the climate on Earth and increases volcanic activity. The last Little Ice Age occurred during a Grand Solar Minimum. But the coming Grand Solar Minimum is going to hit harder because the Earth's magnetic field is at least 30% weaker and, with the ongoing geomagnetic excursion, is continuing to weaken. This will let in more cosmic radiation, which will directly cause mutations, pandemics, cooling, crop failures, and even crustal displacement. Since the advent of modern technology, we haven't experienced either a Grand Solar Minimum or a geomagnetic excursion, and we are due for both.show more

The volatility - yes, volatility - in AR 4366... is absolutely unbelievable. I don't think I have ever used the word 'volatility' to describe an active region. The X-ray flux has been mostly above the M-class threshold for *35 hours* now. There have been 25+ M-class and 4 X-class flares. It is unfortunate that most of these flares are impulsive, else we'd have a train of CMEs en route and likely impacting by now. Even so, the show is incredible, one of the highlights of Solar Cycle 25 - we will be talking about this for a long time!show more

Space Weather picks up in a big way! Region... 4246 launches 4 solar storms towards Earth. Region 4248 &4250 are now entering the same hot longitudes & getting more active. Expect big flares, HF radio blackouts & storm launches to continue! Strong Earth-impacts peak October 15-17.show more

BREAKING! A large wave of plasma launched from the... Sun July 30th has begun sweeping past Earth. Thus far the magnetic connectivity has been strong (Bt ~16 nT, Bz -10 nT | peak Bt 21 nT, Bz -16.5 nT), and I suspect we'll soon be in a moderate to strong G2-G3 geomagnetic storm...show more

The entire month of May 2025 in the Sun’s... atmosphere. Although the Sun produced a few large solar flares, sunspot numbers were the lowest we’ve seen since August 2022. We are likely now slowly moving towards solar minimum, but we still expect large flares throughout this decline!show more

The second of today’s X-class solar flares was truly... a long-duration event. Where typical flares last 10s of minutes, this event took over 6 hours. The flare also showed a fundamental part of solar flares: a ‘current sheet’. #spaceweather 1/5show more

🚨 THE SUN JUST PUNCHED EARTH IN THE MAGNETIC... FACE - AND WE LOVED IT On November 11, the Sun fired off an X5.1 solar flare - the biggest of 2025 - and hurled a plasma freight train at Earth at 600+ km/s. Twenty-four hours later, it slammed into our magnetosphere like a cosmic battering ram. NASA’s model shows it perfectly: Earth, a tiny blue marble at the center… Red zones whipping past like solar shrapnel… Magnetic field lines bending, twisting, screaming under the impact. This is what a geomagnetic storm looks like when the universe decides to remind you who’s in charge. The fallout? Satellites jitter. GPS drifts. HF comms get scrambled. And the sky throws a rave - auroras blooming far south of where they have any business being. With the Sun climbing toward peak activity, this won’t be the last hit. Expect more storms, more skyfire, and at least one “Why is the aurora over Chicago?” moment before 2026 is done. Source: Black Holeshow more

You can see the disturbance from the recent X5... solar flare covering nearly half of the Sun. It produced a fast, full-halo CME with a highly dense core. With two preceding CMEs already on their way, this event will further intensify the geomagnetic activity on an already weakened magnetic field. The earlier CMEs are already arriving, but the one from the X5 flare has not yet reached Earth.show more
