The Sun exploded off another powerful solar flare (6.5... M-class) today October 10th 2026. This struck right when a much stronger than expected (by most) solar storm hit Earth, and as I'm writing this we're now in a G3 strong geomagnetic storm, with the potential for G4 severe levels in the hours ahead...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

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

NOAA's space weather model for the huge solar storm... launched towards Earth forecasts peak impact tonight at 11pm EST (01:00 UTC 01/20), reaching G4 geomagnetic storm levels. We're already in a strong S3 radiation storm. This CME will combine with a CIR, strengthening the impactshow more

Yesterday the Sun unleashed a powerful X1.9-class flare —... one of the strongest in recent times. 🔥 A massive cloud of plasma is already racing toward Earth. Latest calculations suggest the impact on our magnetosphere could hit today around midday. A strong G3–G4 geomagnetic storm is expected — bringing vivid auroras and possible disruptions to communications.show more

The X1.2 flare produced an impressive full-halo CME, with... the bulk directed NW and a notable Earth-directed component. Combined with the previous CME, this event could drive strong geomagnetic activity, strong G3–G4 storm potential.show more

A solar storm impact has arrived as expected, and... now geomagnetic activity is increasing! The storm is dense (~13 /cm3), slow (~420 km/s), and double the strength (~11 nT) of the normal solar wind. Unless it dramatically strengthens we're probably looking at G1 levels at most.show more

.NOAA’s #GOESWest (#GOES18) 🛰️ captured a solar flare occurring... from the sun today using its Solar Ultraviolet Imager (#SUVI). The flare was identified as M-Class—the second most powerful in the classification system—and is generally most visible in the instrument's 131-Angstrom band shown here.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

Yesterday’s near X-class #SolarFlare (M9.75-class) produced a clear CME... and solar radiation storm (causing the fuzzy noise shown in the data). The CME is expected to arrive Monday, with a G2 geomagnetic storm currently predicted. #spaceweather #astronomyshow 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 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

NEW: A solar storm was launched from the Sun... yesterday and is on the way to Earth. NOAA has issued a Moderate Geomagnetic Storm Watch for Friday, October 9 due to anticipated arrival. Community consensus on the arrival of this CME is around the first half of the UTC day on Friday, but our in-house model has the storm arriving near Earth a bit later, closer to 15 UTC. Expected Kp range between 4 and 6. #spaceweathershow more

A whole train of big #solarstorms are on their... way, along with some smaller storms hitting now, and some fast solar wind! It is an #aurora photographers dream starting now and lasting at least through the weekend. Right now, the biggest of the storms should hit late Thursday or early Friday morning and is well-represented in NOAA's prediction model. You can also get a 3D view of the coming solar storm in my earlier post. G3 to G4 storm levels are possible by Friday.show more

Rare red auroras lit up the night sky over... Hanle, Ladakh, after the most intense solar storm in over two decades hit Earth. This stunning celestial show is caused by charged solar particles interacting with our atmosphere, a beautiful yet sobering reminder of solar volatility.show more

.NOAA's #SpaceWeather Prediction Center has issued a G3 (Strong)... Geomagnetic Storm Watch for April 16, after a coronal mass ejection (#CME) erupted from the sun last Sunday. The Solar Ultraviolet Imager (#SUVI) onboard NOAA's #GOESEast 🛰️ captured the Earth-directed double filament eruption. NOAA Space Weather Prediction Center #GOES19show more

WE HAVE IMPACT. The EMP from the solar storm... shockwave spiked the interplanetary magnetic field to Bt 87 nT and Bz -32 nT which is INSANE. We're simultaneously in severe G4 geomagnetic and S4 radiation storms. Now the interplanetary magnetic field is at Bt ~35 nT and Bz -23 nT.show more

The Sun is absolutely COOKING right now. 1 X-flare... and 10 M-flares in less than 16 hours, and this still looks like preliminary activity to stronger solar flares and big coronal mass ejections as active region 4366 has grown significantly since my last update. BOOMSHAKALAKA!!show more
