S3 (Strong) Solar Radiation Storm in Progress / NOAA / NWS Space Weather Prediction Center
S3 (Strong) solar radiation storm conditions were reached the morning of 9 October (Eastern time zone). Storm conditions of at least S1-S2 (Minor-Moderate) are likely to continue into 10-11 October. This event is associated with the X1.8 (R3) solar flare the evening of 8 October and its related coronal mass ejection (CME). Visit our webpage for the latest information and updates about this event.

G4 (Severe) Storm Watch for 10-11 October / NOAA / NWS Space Weather Prediction Center
A fast coronal mass ejection (CME) erupted from the Sun the evening of 8 October, 2024, and is likely to arrive at Earth on 10 October. This CME has been analyzed and speed estimates are 1200 to 1300 km/s. This makes for a potential arrival time as early as the morning to midday of 10 October EDT. There is potential to reach G4 (Severe) upon arrival of this CME and throughout its passage. We won’t know the characteristics of the CME until it arrives 1 million miles from Earth and its speed and magnetic intensity are measured by the DSCOVR and ACE satellites. Please visit our webpage for the latest information and updates.

Comet Tsuchinshan-ATLAS Comes into View of Coronagraph Imagery / NOAA / NWS Space Weather Prediction Center
Comet C/2023 A3 (Tsuchinshan-ATLAS) came into view of the NASA/SOHO Coronagraph on 7 October. The comet’s appearance coincided with an X2.1 (R3-Strong) flare and a pair of coronal mass ejections (CME). The comet will continue to pass from the right to the top left of the Sun into October 10th before it moves out of view by October 11th. During its transit across the coronagraph imager, it will continue to be a magnificent presence, but could over-saturate imagery due to its tremendous brightness.

Strong Solar Flare Erupts from Sun – Solar Cycle 25 • NASA
Strong Solar Flare Erupts from Sun
The Sun emitted a strong solar flare, peaking at 5:43 a.m. ET on Sept. 12, 2024. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

The Sun, shown in hues of gold, pink, and blue. There are many active regions on the Sun. They appear bright, as light from those areas cascades into space around the star. On the far left of the Sun, a bright flash of light in pinks and blues is apparently against the dark background of space.
NASA’s Solar Dynamics Observatory captured this image of a solar flare — seen as the bright flash on the left — on Sept. 12, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in gold. Credit: NASA/SDO
Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X1.3 flare. X-class denotes the most intense flares, while the number provides more information about its strength.To see how such space weather may affect Earth, please visit NOAA’s Space Weather Prediction Center https://spaceweather.gov/, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts.

CMEs arrived on 11 Aug and Passage Continues - G4 (Severe) Reached / NOAA / NWS Space Weather Prediction Center
Between August 8-10, 2024, five Coronal Mass Ejections (CMEs) were observed leaving the Sun, prompting geomagnetic storm watches. The CMEs reached Earth over the weekend (August 11-12). CMEs, which are massive eruptions of solar material, can trigger geomagnetic storms upon arrival at Earth, potentially impacting various technologies. Geomagnetic storm conditions steadily intensified throughout the weekend into early Monday, culminating in a G4 (Severe) Geomagnetic Storm shortly before 1500 UTC. The SWPC has maintained continuous communication with power grid reliability coordination centers. This level of storming also causes HF communications degradation at high latitudes and increased satellite drag in low Earth orbit. Conditions are expected to persist into Tuesday, but the duration of CME impacts and the favorability of solar wind conditions remain highly uncertain. These conditions are part of the ongoing Solar Cycle 25, which has reached one of its highest levels of sunspot activity in over 20 years.

Solar activity was elevated through the weekend and various eccvents, including solar flares and filament eruptions were associated with CMEs. Some of these CMEs were determined to have Earth-directed components and arrival could begin as early as July 29th due to an event early on 27 July. Additional CMEs recently departed the Sun and are expected to arrive July 30th and continue into July 31st. Any CME arrival on 29 July could result in G1 (Minor) storm levels, however, the brunt of the activity is most likely on 30 July when additional CMEs from 27-28 July arrive and this could lead to G2-G3 levels as indicated by the WSA-Enlil model. CME influences will likely continue into 31 July as it takes time for CMEs to progress over and past Earth. Still, additional CMEs continue to erupt from the Sun due to the number of active regions and the associated complex sunspot groups, and additional CME arrivals are possible. Flare probabilities have increased and M-class flares (R1-R2; Minor-Moderate) events are now expected through most of the week, with a slight chance to chance of X-class activity (R3; Strong).

Active Region 13664 was responsible for the largest geomagnetic storm of Solar Cycle 25, read the story from an operational perspective HERE:
The Evolution and Impact of Active Region 13664

A group of sunspots, designated as NOAA Active Region 13664 was identified as a substantial and complex sunspot group during the first week of May 2024. The region produced several solar flares and Earth-directed coronal mass ejections (CMEs) which led to the onset of extreme geomagnetic storming conditions; the strongest since the Halloween Solar Storms of 2003. These storms caused widespread auroras, disruptions in satellite operations and communications, potential power grid issues, and increased radiation hazards for space missions and high-altitude flights. Active Region 13664 returned twice, renumbered as Active Region 13697, which produced the largest proton event of Solar Cycle 25, and again as Active Region 13723. This story is written from the view of an operational forecaster at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center in Boulder, Colorado.

G3 (Strong) Levels Reached on 28 June / NOAA / NWS Space Weather Prediction Center
G3 (Strong) storm conditions were reached about 9:28am EDT on June 28th. The increased geomagnetic activity was in response to the arrival of a coronal mass ejection (CME) that departed the Sun on June 25th. The CME was associated with a large filament eruption and analysis indicated a possible Earth arrival as a glancing blow today. Indeed, a disturbance in the solar wind was observed by an observation satellite one million miles from Earth at 5:12am EDT. This was the leading edge of the CME and when it arrived at Earth, geomagnetic conditions quickly intensified and eventually reached G3 levels. The G3 Warning is in effect until 5:00pm EDT as CME passage is anticipated to continue through the day. There will likely be variable conditions of geomagnetic response during CME progression, so continue to monitor our SWPC webpage for the latest information and updates.

The Sun unleashed a series of X-class flares (R3; Strong) from 5 to 6 May, 2024. Multiple M-class flares (R1-R2; Minor-Moderate) events have also occurred since May 5th. However, intensity of the flares first breached R3 thresholds on May 5th at 2:01 EDT (0601 UTC) with an X1.3 flare. An X1.2 flare occurred later at 7:54am EDT (1154 UTC). The most recent X-class flare reached X4.5 on May 6th at 2:35am EDT (0635 UTC) - the strongest of this series of flares. However, this was not the strongest flare of Solar Cycle 25 thus far - that honor is still held by an X6 flare on February 22nd, 2024. The current source of the strong flare activity is NOAA/SWPC Region 3663, a complex sunspot cluster over the northern solar hemisphere. There remains a continuing likelihood of additional M-class flares, with a good chance of additional X-class flares over the next three days.

The total solar eclipse will be a great time for science from the backyard. During totality, what will the Sun’s corona look like? Might there be a coronal mass ejection departing the Sun? Could there be a massive solar prominence suspended above the solar disk? These are some of the things to look for when the Sun is completely eclipsed by the Moon (the only safe time to look at the eclipse is during totality). The total solar eclipse of 2017 revealed the Sun’s corona in all its glory as captured in the NOAA/SWPC employee photograph. When their photo was aligned and compared to the NASA/SOHO coronagraph imagery for the same time (with the help of jhelioviewer), the three coronal streamers evident from the spacecraft 1 million miles from Earth were also visible from the surface of Earth at the same time. Science from the backyard! Enjoy the event everyone and most of all, be safe.

Photographing Auroras

An aurora is a natural light display predominantly seen in the polar regions, caused by the interaction between the Earth’s magnetic field and charged particles from the Sun. These particles are carried towards the Earth by the solar wind and are mostly electrons and protons. When these charged particles collide with gases in the Earth’s atmosphere, they excite the atoms, causing them to light up. The auroras occurring around the north pole are known as Aurora Borealis or Northern Lights, while those around the south pole are called Aurora Australis or Southern Lights. These displays can vary in color and complexity, from faint glows to rapidly shifting ribbons of light, depending on the type of gas particles involved and their altitude. This celestial phenomenon is not only a beautiful natural spectacle but also part of the larger space weather system that can affect satellite operations and power grids on Earth.

Solar Dynamics Observatory News

The Solar Dynamics Observatory (SDO) is a NASA mission launched in February 2010 as part of the Living With a Star (LWS) program, which aims to understand the causes of solar variability and its impacts on Earth. The SDO is equipped with three advanced scientific instruments: the Helioseismic and Magnetic Imager (HMI), the Atmospheric Imaging Assembly (AIA), and the Extreme Ultraviolet Variability Experiment (EVE), which together provide comprehensive measurements of the sun’s interior, atmosphere, magnetic field, and energy output. Operating in a geosynchronous orbit around Earth, the SDO supplies high-resolution images of the Sun in multiple wavelengths, offering unprecedented insights into solar activities such as solar flares, coronal mass ejections, and their effects on space weather. This continuous stream of data plays a crucial role in improving our understanding of the relationship between the Sun and the Earth’s environment.
