Große Prominenzeruption - Eine CME, die durch die riesige Eruption erzeugt wird, könnte der Erde einen flüchtigen Schlag versetzen

Large Prominence Eruption: This event took place earlier today (April 9)
and extended millions of kilometres into space. GOES-16 SUVI captured the event in extreme ultraviolet light. NASA’s Solar Dynamics Observatory was also captured the large eruption.

When a prominence erupts, the released material is part of a larger magnetic structure called Coronal Mass Ejections (CMEs). When directed toward Earth, CMEs can interact with our Earth’s magnetic field and trigger a geomagnetic storm, with bright auroras and the potential for disturbance in communications and electrical power networks.

NOAA forecasters await fresh data from SOHO coronagraphs to confirm if the CME has an Earth-directed component.

Thanks for watching!

#42 Starker geomagnetischer Sturm der G3-Klasse im Gange - Aurora Alert

Starker geomagnetischer Sturm der G3-Klasse im Gange - Aurora Alert
(Strong G3-Class Geomagnetic Storm Underway - Aurora Alert)

G3 (Strong) Geomagnetic Storms were observed at 10/05:10 UTC (1:10 a.m. EDT). A strong G3-class geomagnetic storm is underway on April 10th as Earth passes through the magnetized wake of a CME. The CME struck Earth's magnetic field two days ago. Initially the weak impact had little effect, but a storm has been brewing ever since and it has finally begun. High-latitude sky watchers should be alert for auroras.

The G3 Warning is valid until 10/09:00 UTC (5:00 a.m. EDT).

Active sunspot complex AR2993-94, which unleashed an X1-flare on April 17th, may be just the beginning. NASA's STEREO-A spacecraft is monitoring another potentially large active region right behind it. Stay tuned for more sunspots emerging over the sun's northeastern limb later today or tomorrow.

Region 2992 produced an M1.5 at 17/20:02 UTC and an M4.4 at 17/22:34 UTC. A pulse of X-rays from the M4.4 flare produced a shortwave radio blackout over Hawaii, Micronesia and Polynesia. Mariners, aviators, and ham radio operators may have noticed unusual propagation effects at frequencies below 25 MHz.

Increased solar activity continues. This time it was AR 2992 nearing the southwest limb getting into the action. Moderate to Strong solar activity will remain possible during the next 24 hours with both AR 2993 and 2994 being the most likely threat as they continue to rotate further into direct view.

An M1.1 flare (R1-Minor Radio Blackout) occurred at 1:14 am EDT (0514 UTC) on 22 April, 2022. The flare may have caused weak, minor degradation of HF radio communication or occasional loss of contact on the sunlit side of Earth – which at the time of the flare was over large portions of Asia and Australia [as seen in our D-RAP model near the peak of the flare]. Low-frequency navigation signals may also have been temporarily degraded for brief intervals over the same sunlit areas.

The moderately complex Region 2994 was the source of the flare and further flares of this level are still expected over over the next three days, with a chance for higher level activity. https://www.swpc.noaa.gov/

NO CMEs ARE HEADING FOR EARTH: So far this week, the sun has produced dozens of solar flares. Zero debris is heading our way. Remarkably, all of the explosions have been off target. Active sunspot complex AR2993-94 is still turning toward Earth, however, so the odds of a future hit are increasing.

Sunspots AR2993-94 are crackling with M-class solar flares. The explosion, which peaked on April 22nd at 1325 UTC, registered M3.4 on the Richter Scale of Solar Flares.

A pulse of X-rays and UV radiation briefly ionized the top of Earth's atmosphere, causing a minor shortwave radio blackout over the mid-Atlantic Ocean.

There might be a CME. Confirmation awaits fresh data from SOHO coronagraphs.

A near X-Flare (M9.6) just peaked at 01:58 UTC (Apr 21) around Earth facing sunspot region 2993. This region is now in a good position for Earth directed eruptions. First analysis is that a potential CME is likely. Any ejected material may be Earth directed.

R2 (Moderate) Radio Blackout
Radiation from the flare caused a shortwave radio blackout over Australia, SE Asia, China, Siberia, Hawaii and Micronesia. Mariners and ham radio operators in the area may have noticed loss of radio contact at frequencies below 30 MHz.

Active Region 3004 unleashed a strong M5.7 solar flare, with a peak time of 4:59 a.m. EDT (08:59 UT). There was a small dimming associated with the flare, meaning that a coronal mass ejection associated with this event. Given the location of the region near the central meridian, any associated eruption could impact Earth. Further analysis of any associated eruption will be given when the coronagraph data become available.

R2 Moderate Radio Blackout
Radiation from the flare ionized the top of Earth's atmosphere, causing a shortwave radio blackout over India/Indian Ocean/Africa/Europe/Western Russia and Middle East.

Solar flaring activity was high over the past 24 hours. An X1.1 flare was observed from beyond the east limb, peaking at 9:25 a.m EDT (13:25 UT). This region, which is just rotating onto the disk, also produced an M5.3 flare at 00:19 UT (May 4).

M-class flares (R1-R2 Minor-Moderate radio blackouts) are likely over the next three days (04-06 May) with ongoing activity in the southeast quadrant,
and an increase in activity from Region 3004. There is a chance for R3 (Strong) or greater Radio Blackouts as well.

Since yesterday, big sunspot AR3014 has doubled in size. This 24-hour movie from NASA's Solar Dynamics Observatory shows the sunspot's rapid growth. AR3014 has a 'beta-gamma' magnetic field that harbors energy for strong M-class solar flares.

There is a chance for M-class flares (R1-R2; Minor-Moderate radio blackouts) and slight chance for X-class activity (R3; Strong) 18-20 May.

Spectacular Eruption - May 18, 2022
A NOAA spacecraft watching the sun has caught a dazzling view of a solar eruption that launched a vast tendril of magnetic plasma into space.

Yesterday, a magnetic filament on the sun erupted, hurling a faint CME into space. NOAA forecasters say it could hit Earth's magnetic field on June 5th or 6th. Even weak CME strikes can cause geomagnetic storms, so there is a chance of minor G1-class storms when the CME arrives.

A new sunspot is emerging in the sun's southern hemisphere--and it's a little strange. For one thing, it is circular. For another, its magnetic field is tilted 90 degrees away from normal sunspots. This one merits watching.

Filament Eruption and CME
A large filament eruption was detected in the sun's northern hemisphere in the late hours of June 8. The CME that left the Sun will not be Earth directed.
