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

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:

enter image description here

#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.

#X-CLASS #SOLARFLARE: As predicted, strangely-magnetized sunspot AR3784 (described below) produced an X1-class solar flare today. The explosion was directly facing #Earth:

#Radiation from the flare ionized the top of Earth's atmosphere, causing a deep shortwave radio blackout over India and the Middle East: map. The explosion might have hurled a faint halo CME toward Earth, but the jury's still out.

#X-CLASS #SOLARFLARE: Departing sunspot AR3664 (3697) produced another #X-flare today (1108 UT). The X1.5-class explosion occured just beyond the sun's western limb, and was partially eclipsed by the edge of the sun. As a result, it was not very geoeffective. The explosion did not reverse the decline of an ongoing radiation storm (described below), nor did it produce an Earth-directed CME.

Sunspot AR3664 just did it again. The record-setting active region produced another very strong #solarflare on June 8th (0149 UT). NASA's Solar Dynamics Observatory recorded the category M9.7 blast:

Extreme ultraviolet radiation from the flare ionized the top of Earth's atmosphere, causing a deep shortwave radio blackout across the western Pacific Ocean: map. Mariners and ham radio operators may have noticed loss of signal at all frequencies below 30 MHz.

Of greater interest is the radiation storm. Energetic protons accelerated by the flare are raining down on #Earth and hitting all satellites in the vicinity of our planet.
Every speck of 'snow' in this SOHO coronagraph movie is caused by an energetic proton striking the spacecraft's camera:

ANOTHER #X-FLARE: Old sunspot AR3664 (now AR3697) isn't as big as it used to be, but it is still very active. Today at 1437 UT, it produced an #X1.4-class #solarflare:

Note: The jiggling of the #sun in this movie is not caused by the X-flare. Calibration offsets were underway during the flare.

Extreme ultraviolet radiation produced a deep shortwave radio blackout over the Americas. Ham radio operators may have noticed loss of signal at all frequencies below 30 MHz.

This long-duration flare almost certainly hurled a CME into space. The US Air Force is reporting a Type II solar radio burst most likely produced by shock waves in the leading edge of a CME. Within the radio burst, frequency drift rates suggest an expansion velocity near 900 km/s (2 million mph). Confirmation awaits fresh data from SOHO coronagraphs.

#Sunspot AR3664, the source of the historic May 10th superstorm, has spent the past two week's transiting the farside of the #sun. Yesterday, it announced its return with an #X2.8-class #solarflare. Amateur #astronomer Michael Karrer was watching the sun when the #explosion occured, and he captured this #picture of flying debris:

"I have not seen an explosion like this in my 40 years of observing the sun," says Karrer. "So fast, so far out into space! It was gigantic."

The explosion caused a deep shortwave radio blackout over east Asia and hurled a bright #CME into #space. A NASA model of the CME confirms that it will miss Mercury, Venus and Earth. None of the inner planets will be affected by this powerful event.

STRONGEST #SOLAR #FLARE OF THE CURRENT CYCLE: #Sunspot AR3664 just unleashed the strongest #solarflare of the current solar cycle--an #X8.7-category blast from beyond the sun's western limb. #X marks the spot in this image of the flare from NASA's Solar Dynamics Observatory:

Because the sunspot is behind the edge of the solar disk, the flare was partially eclipsed. It was probably even stronger than it appeared. "X8.7" is almost certainly an underestimate of the flare's true strength.

Extreme ultraviolet radiation from the flare ionized the top of Earth's atmosphere, causing a deep shortwave radio blackout over the Americas. Ham radio operators, aviators and mariners may have noticed a sudden loss of signal at all frequencies below 30 MHz.

Subatomic debris from this event might soon reach Earth, guided toward our planet by the Parker Spiral

Big #sunspot AR3590 is as dangerous as it looks. Late yesterday (Feb. 21 @ 2307 UT), the active region produced a powerful X1.8-class #solarflare with a shortwave radio blackout over the western USA and Pacific Ocean. NASA's Solar Dynamics Observatory recorded the extreme #ultraviolet #flash:

enter image description here

The explosion did not produce a CME, at least not a bright one. NOAA analysts are still inspecting SOHO coronagraph data for signs of a storm cloud. If they find one, it will be reported here.

This could be the first of many flares from AR3590. The sunspot has an unstable 'beta-gamma-delta' magnetic field that harbors energy for multiple #X-class #explosions

Yesterday, a pair of bright #CMEs left the #sun. Both are off target:

The CME on the right is debris from a magnetic filament, which erupted near the sun's southwestern limb on Sept. 23rd (1330 UT). The #CME on the left came from new sunspot AR3110. An M1-class #solarflare hurled it into #space (1810 UT). The bright light at 3 o'clock is Venus. None of these things will hit our planet.

The sun can't keep missing forever, can it? Active sunspot AR3110 is turning toward #Earth and will soon be in the strike zone
