I am absolutely entranced by this swirling plasma left behind after the flare blasts through. The way they swirl reminds me of like a vortex dipole, or maybe even a smoke ring. Very aesthetic eruption

BOOM 1.31 X-Flare just blasted off from our new active sunspot rotating in! While our crop of super-active sunspots is rotating out, it appears the big solar flares aren't coming to an end any time soon...

[Jure Atanackov @JAtanackov]

BOOM! X1.3 flare from an incoming active region on the E limb. That's the complex region that we have been tracking for about a week now.

[Jure Atanackov @JAtanackov]

BOOM! The X1.3 flare on the E limb (from the newly numbered AR 4482) is eruptive, with the lifting CME clearly visible in GOES SUVI 284A data. More soon!

[SpaceWeatherLive @_SpaceWeather_]

The X1.3 flare that peaked today at 20:41 UTC came from newly numbered Sunspot Region 4482. Not 4479 as our automated detection wants you to believe. Could this be the next sunspot region that will produce high solar activity in the next 2 weeks?

Massive thanks to SpaceWeatherLive forum user ColaSun for this awesome compilation of SDO imagery of the eruption.

X1.3 solar flare detected at 20:41 UTC (July 4th). The source is a new region turning into view from off the east limb. https://t.co/aqK4Q6XdAY

A new active region has generated an X1 class flare on the southeast side of the sun, a CME is observed

Some 190 million light-years away, far beyond the bright stars and nebulae of the Milky Way, these three galaxies are drawn together by gravity in a mesmerizing cosmic dance.

Clearly distorted by galactic-scale gravitational interactions, large spiral galaxies NGC 6769 and NGC 6770 are seen face-on, with luminous galactic disks scarred by obscuring interstellar dust lanes.

Their young blue star clusters along drawn out spiral arms are spawned in star forming regions that resulted from collisions of massive molecular clouds. Below, spiral NGC 6771 presents a more edge-on perspective, its boxy central bulge due to tidal star streams. Of course, in the distant future a merger of the three galaxies is inevitable.

At the estimated distance of this galaxy trio, known to some as the Devil's Mask, the sharp telescopic frame spans over 300 thousand light-years within the boundaries of the far southern constellation Pavo.

Double M flare earlier on the limb! The second one looks to have fired something off. Not even close to Earth-directed, just a cool loop I really enjoyed seeing!

Just 1.4 billion years after the Big Bang, a massive galaxy may be losing the gas that makes stars, with more than half its cold gas pulled into a long, calm tail. @arxiv https://t.co/MlfOxvZ0tb

Here's the uncropped image from the video I shared yesterday, showing this massive wave of energy traveling through interstellar space after a supernova.

This is a 65 hour exposure captured entirely from my backyard.

Two strong eruptive M-class flares: M6.7 from AR4479 and M6.3 from AR4478. The resulting CMEs are mainly west-directed and are unlikely to have an Earth-directed component.

[ESA Space Weather @esaspaceweather]

The X1.1-flare CME from AR4479 on 30 Jun has likely recently arrived at L1, as of 03/1119 UTC. This was a partial halo CME with an Earth-directed component, arriving a little later than previously expected. Solar winds are now Slightly Elevated, around 450km/s.

The CME associated with the X1.1 solar flare on June 30th is now arriving. A passage past Earth is expected within the hour. https://t.co/aqK4Q6XdAY

Sister ship Voyager 1 is currently ~23h 36m 15s of light travel time from Earth (2026:184:120000:1L)

[Jure Atanackov @JAtanackov]

Impact! A CME leading edge has just passed L1 (11:16 UTC). Solar wind speed rapidly increased from ~400 km/s to ~500 km/s, Bt jumped nearly 15 nT. This is likely the CME from the X1.1 flare in AR 4479 on Wednesday. Expecting the CME to reach the Earth about 50 minutes after L1, so around 12:05 UTC. Let's keep an eye on the solar wind and how the CME evolves - don't forget, there is a G2 (moderate) storm watch in effect today!

Located roughly 460 light-years away in Taurus, the molecular cloud L1527 hosts a protostar and shows a faint blue haze plus filamentary PAH (polycyclic aromatic hydrocarbon) emission.
