A #CME was supposed to narrowly miss #Earth today. Instead, it delivered a direct hit. The impact on Dec. 17th (0519 UT) sparked a #G1-class #geomagnetic #storm with bright #auroras over #Alaska:
"The reds were fully visible to the eye!" says photographer Sacha Layos of Fairbanks, AK. "A complete treat for the eyes and soul."

ARCTIC #AURORAS: As expected, a #CME hit #Earth on Nov. 7th. The glancing blow was so subtle that, at first, it did not trigger our CME alarms. As Earth moved into the CME's wake, however, it became clear that a solar storm had arrived. Auroras spread around the Arctic Circle, including these over Fáskrúðsfjörður, #Iceland:
"Beautiful #Northern-Lights could be seen tonight despite the clouds," says photographer Jónína Óskarsdóttir. "It was very windy and +11°C, which is unusual in November."

https://vmst.io/@WestportObservatory/113375307995062785 WestportObservatory@vmst.io - AN X-CLASS DOUBLE SOLAR FLARE: Solar activity remains high with an X-class double solar flare on Oct. 26th. The explosion hurled an impressive CME into space, and it appears to have an Earth-directed component. Several big sunspots are turning toward Earth, so this could be the beginning of a week of stormy space weather. Also, a CME grazed Earth today, 10/26. The impact was weak, barely increasing solar wind speeds near Earth. High-latitude auroras are possible tonight. Spaceweather.com

#X-CLASS #SOLAR #FLARE: Emerging #sunspot AR3869 erupted this morning (Oct. 24th @ 0357 UTC), producing a slow X3.3-class solar flare. NASA's Solar Dynamics Observatory recorded the hour-long flash:

6-hr max: X3 0357 UT Oct24
24-hr: X3 0357 UT Oct24
Extreme #ultraviolet #radiation from the flare ionized the top of #Earth's atmosphere. This, in turn, caused a shortwave radio blackout over Australia and Southeast Asia. Ham radio operators may have noticed loss of signal at frequencies below 30 MHz for as much as an hour after the flare.
This explosion almost certainly produced a #CME. The US Air Force is reporting a Type II solar radio burst, a natural signal that comes from shockwaves at the leading edge of CMEs. Characteristics of the burst suggest a CME traveling 1.3 million mph.
#X-CLASS SOLAR #FLARE: #Sunspot AR3848 was directly facing #Earth this morning, Oct. 8th (0156 UTC), when it unleashed a powerful X1.8-class solar flare. NASA's Solar Dynamics Observatory recorded the extreme #ultraviolet #flash:
This explosions lasted more than 4 hours, so long that it lifted a massive CME out of the #sun's atmosphere. Take a look at these preliminary coronagraph images from NASA's STEREO-A spacecraft. This #CME will certainly hit Earth later this week, potentially sparking a new round of geomagnetic storms.

#CME COULD HIT #EARTH AND #COMET T-ATLAS: SOHO coronagraphs are obtaining some remarkable images today. One of the brightest comets in decades, Comet Tsuchinshan-ATLAS (C/2023 A3), is passing through the field of view while the sun emits a series of bright CMEs. The first CME in this movie appears to be on course to hit both Earth and the comet:
Hurled into space by a powerful X2-class solar flare on Oct. 7th, the CME could strike the comet later today or perhaps early on Oct. 9th, The impact could actually rip off the comet's tail. The same thing happened to Comet Enke in April 2007. A broken tail is something astronomers should look for when Comet Tsuchinshan-ATLAS emerges from the sun's glare later this week.
According to a NASA model, the CME will graze Earth late on Oct. 9th or early on Oct. 10th. The impact could cause a another geomagnetic storm with auroras at mid-latitudes in the USA and Europe. NOAA analysts are looking at this CME now and may soon issue a refined forecast

HE STRONGEST #FLARE YET: Sunspot AR3842 exploded again today, producing the strongest #solarflare of Solar Cycle 25 so far. NASA's Solar Dynamics Observatory recorded the #X9.1-category blast:
#Radiation from the flare ionized the top of #Earth's atmosphere and caused a deep shortwave blackout over Africa and the South Atlantic. Ham radio operators in the area may have noticed loss of signal at frequencies below 30 MHz for as much as a half an hour after 12:18 UTC.
Of greater interest is the #CME. Preliminary SOHO coronagraph images show a halo CME emerging from the blast site. This CME will probably strike Earth on Oct. 6th, adding its effect to that of an earlier CME expected to arrive on Oct. 4th. #Auroras are therefore likely this weekend.

POSSIBLE EARTH-DIRECTED EXPLOSION: Surprising forecasters, who thought sunspot AR3835 was too stable to explode, #sunspot AR3834 exploded on Sept. 22nd (2139 UTC). The M3.4-class #flare hurled a massive plume of #plasma into space:
Debris from the blast entrained even more plasma on its way out of the sun's atmosphere, forming a partial halo CME. The bulk of the #CME will miss Earth, but its flank will deliver a glancing blow to our planet on Sept. 25th,
ANOTHER EARTH-DIRECTED EXPLOSION: #Sunspot AR3814 has a mixed-polarity magnetic field that makes it a threat for strong flares. This morning, it exploded while directly facing #Earth:
The #ultraviolet #flash (category M1.2) ionized the top of Earth's atmosphere and caused a brief shortwave radio blackout over the Pacific Ocean. Mariners and ham radio operators may have noticed loss of signal at frequencies below 20 MHz between 00:15 and 01:00 UT.
Of greater interest is the #CME. SOHO coronagraphs detected a full halo CME moving directly toward Earth. A NASA model suggests it will reach our planet during the late hours of Sept. 12th. The impact could cause a G2-class geomagnetic storm.

FARSIDE EXPLOSION CAUSES #RADIATION STORM: Protons are raining down on #Earth today following an explosion on the farside of the sun. It's an S1-class solar radiation storm. The farside blast hurled a magnificent #CME into space, recorded by the Solar and Heliospheric Observatory (SOHO):
Shockwaves in the leading edge of the CME accelerated the protons and scattered them throughout the solar system--even toward Earth on the opposite side of the sun. Our planet's magnetic field is capturing the particles and funneling them toward the poles, where they are causing a polar cap absorption event

PUFF OF DARK #PLASMA IS HEADING FOR EARTH: A filament of magnetism erupted on the Sun Sept 8th. The blast hurled a coil of cool dark plasma toward #Earth:
NASA's Solar Dynamics Observatory recorded the explosion. The departing plume ripped a hole in the sun's atmosphere and formed the core of a coronal mass ejection (CME). NOAA models suggest that the #CME will reach Earth late on Sept. 10th, potentially sparking a G2-class geomagnetic storm.

#CME IMPACT SPARKS GEOMAGNETIC STORM: Geomagnetic storms are underway following the arrival of a CME on Aug. 27th. At first, the CME's impact appeared weak and, indeed, it did not cause an immediate geomagnetic storm. Since then, however, magnetic fields in the CME's wake have linked to Earth's magnetic field, causing storms of category G2 (with a chance of G3) on Aug. 28th. CME impact alerts: SMS Text
"This morning, on August 28, 2024, around 1 AM (UTC) faint #auroras appeared over the #Czech-Republic," reports Petr Horálek, who sends this picture from the shore of Seč Lake:
"What a year, so many auroras from central Europe have not been visible since 2001!" he says.

GEOMAGNETIC STORM WATCH (G3): A series of three CMEs is now heading for Earth. The first two, launched by M-class flares on August 7th, are relatively minor. The third, launched by yesterday's #X-flare (described below), is more potent. Striking Earth in succession on Aug. 9th, 10th, and 11th, the three CMEs could spark geomagnetic storms as strong as category G3 with mid-latitude auroras in the USA and Europe.

X-CLASS SOLAR FLARE AND HALO CME: Active sunspot AR3777 just produced its most powerful solar flare yet--an X1.3-class explosion on Aug. 8th (1935 UT). NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:
Radiation from the flare ionized the top of Earth's atmosphere and caused a shortwave radio blackout from North America to the Hawaiian islands. Mariners and ham radio operators may have noticed loss of signal below 30 MHz for as much as an hour after the flare.
Of greater interest is the coronal mass ejection (CME). Soon after the flare, SOHO coronagraphs detected a halo #CME heading straight for #Earth:
The Cannibal #CME is clearing the way for perhaps 2 to 3 more CMEs following behind it. SOHO coronagraphs show a wagon-train of clouds leaving the #sun on July 28th:
The first and most potent of these CMEs was launched by an M9.9-class solar flare from sunspot complex AR3765-67 on July 28th (0157 UT): movie. The CME will fly into a void created by the earlier Cannibal CME. With little interplanetary material to slow it down, the storm cloud should reach Earth no later than July 31st. A preliminary NASA model supports this forecast.
Even if the Cannibal CME fails to spark a strong geomagnetic storm on July 30th, the arrival of more CMEs on July 31st could push storm levels to category G3 (Strong) or beyond. This would set the stage for mid-latitude auroras visible from Europe and the USA
