The Sun emitted a strong solar flare on Oct. 3, 2024, peaking at 8:18 a.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X9.0: go.nasa.gov/4gOCP7u pic.x.com/vepjmFZ623

We gotta hand it to this solar active region. No hesitating, no messing around: it has only produced a *single* X-class #SolarFlare to date, and it was that flare that gave us the Earth-directed CME that caused last night’s *extreme* geomagnetic storm! pic.x.com/OcMVX4CRK3

Aloha〜🤙 目に見えているものより見えないものの方が大切だったりしますね。 本日も寒暖差に対応して心穏やかに〜 pic.x.com/L6BFeHbZmg

The ongoing X1.8-class #SolarFlare, so far. This is a long duration event, likely persisting for a few more hours yet. I’m blown away by the size of the ‘flare ribbons’, briefly seen extending to the north of the main flare region! #astronomy pic.x.com/X5GxTs4Lbb

An X-class #SolarFlare is currently in progress on the Sun! This event is from a different region to the previous three X-class events, this time from an Earth-facing region in the northern hemisphere. #spaceweather pic.x.com/pJeYARCrdH

Thursday’s X9 #SolarFlare was captured by the NASA IRIS mission! IRIS observes the Sun with much higher resolution than the flare images you typically see, but over a small region. It can also observe the flare core without saturating the images! #astronomy #spaceweather pic.x.com/n6iHhM95hZ

Early data seems to suggest an eruption from today’s X9 #SolarFlare! Given the flare’s location on the Sun, it’s *more likely* to be Earth-directed than not. But, this is early data, and the event is yet to be modeled. Let’s wait for more data & models before getting too excited! pic.x.com/x0C3wsZGQb

【速報】 本日21:18（世界時12:18）活動領域13842でX9.0の大規模フレアが発生しました。同領域では今月1日にX7.1が発生しており極めて活発な状態です。 動画はNASAのSDO衛星が極端紫外線で撮影したものです。（Courtesy of NASA/SDO and the AIA, EVE, and HMI science teams."） #太陽フレア pic.x.com/hlwCkdNpsW

Woah! What a flare! In addition to the X7 #SolarFlare from earlier this week, the same region on the Sun just produced an X9 flare, the *largest* solar flare we’ve seen since 2017! We await further data to determine if it produced an eruption. #spaceweather #astronomy pic.x.com/FVKpamTBTW

The month of September 2024 in the Sun’s atmosphere! It was a quieter month than earlier this summer, with lower sunspot levels and #SolarFlare levels. But with a large X7-class flare yesterday, will things continue to ramp up again this month? #astronomy pic.x.com/8pTWeqkJBf

Here is a full movie of tonight’s large X7-class #SolarFlare, showing 3 hours of data! This was the second largest flare in 7 years, and we can almost-certainly expect more activity from this region in the coming week. #astronomy #spaceweather pic.x.com/UqnRItfN0A

A significant #SolarFlare is currently in progress on the Sun, producing a widespread strong radio blackout on the day-lit side of the Earth. The flare clocked in above an X7-class, making it the second largest event since 2017. #spaceweather #astronomy pic.x.com/Xj7xpIIWtQ

A subtle #SolarFlare from today, mostly hidden round the back of the Sun. The event still produced a sizeable coronal mass ejection, although it is not directed towards Earth! The source region of this flare will rotate to face us in the coming days. #spaceweather pic.x.com/otqvtci5y3
