The magnetic storm reached a strong G3 level and became the most powerful in 2 months
The geomagnetic storm, which began yesterday around 11:00 PM Moscow time, has now lasted for approximately 11 hours. Last night, the event crossed the psychologically significant G3 threshold, which separates severe storms from moderate-level events.
The strongest magnetic storm in two months is expected on Earth tonight
A magnetic storm is expected to begin today, predicted to be the strongest since mid-January of this year. The storm is the result of a combination of factors, the most important of which are several plasma ejections observed on the Sun earlier this week.
Comet C/2026 A1 continues to fly toward its death
Comet C/2026 A1 continues to move toward its fate, which, unfortunately, currently appears to be extremely bleak. In just 18 days, on April 4 at approximately 5:00 PM Moscow time, the celestial body will make a close approach to, or even impact, the Sun.
A strong magnetic storm is expected on Thursday, March 19
A more or less finalized calculation model for the solar flare and mass ejection that occurred yesterday has been developed, showing a fairly plausible result. The mass ejection is expected to arrive at the planet on Thursday, March 19, 2026, between 4 and 6 a.m.
A major solar flare ejected mass toward Earth
An unexpectedly powerful M2.8 solar flare was recorded by multiple tracking devices. The peak of the event was observed at 3:15 PM Moscow time. The explosion occurred near the center of the solar disk and was accompanied by an obvious ejection of plasma toward Earth.
Comet 3I/ATLAS will pass at its closest distance from Jupiter today at 15:20 Moscow time
The final significant event in the eventful life of comet 3I/ATLAS—its closest approach to the solar system's largest planet, Jupiter—will occur today at 3:20 PM Moscow time.
The brief surge in solar and geomagnetic activity seen over the weekend has ended
After a couple of days of mild turbulence over the weekend, calm and tranquility returned. The Sun's energy levels were still low, and they didn't last long. The star managed to produce two unconvincing flares of M1.2 and M1.0 classes, as well as a significant number—at least 30—of weak C-class flares.
The first long-lasting magnetic storm of spring is occurring on Earth
A planetary magnetic storm has been registered since approximately midnight Moscow time. The event is associated with a sharp increase in solar wind speed near Earth, which, in turn, is caused by a coronal hole on the Sun.
The Sun experienced its first strong flare in 3 weeks
Information has been received about a recently recorded M-class solar flare. The maximum radiation was reached at 12:55 Moscow time. The flare lasted approximately 20 minutes.
Today marks the beginning of a long series of geomagnetic disturbances due to a coronal hole formed on the Sun
The forecast predicts an increase in the speed of the electromagnetic wind flow approaching Earth within 24 hours. Geomagnetic indices should also begin to rise following this. The source of the expected disturbances is clearly visible on the Sun. This coronal hole is quite close in size and not quite solid in shape.
