Surprise Storm: The moderate (G2) geomagnetic storm threshold was reached at 14:56 UTC (Jun 7). This was following a prolonged period of southward Bz that reached -15 nT. It has since shifted back to the north, so this storm should be short lived. As always, further updates will be provided when necessary. Not good timing for aurora sky watchers across Europe and North America..

I like how that flare is like ten times the size of Jupiter, if not more.
The EM field stuff is so amazingly wild. |

This resulted in a large eruption of plasma as seen here in the latest image courtesy of GOES-16 SUVI. Because the event took place towards the southwest limb, it should be mostly directed towards the west and away from Earth.

After first turning into view on May 1st, it would continue to grow and go on to produce twelve X-Flares during the first transit. After rotating onto the farside of the Sun on May 14th, it would reappear again on May 28th. Another five X-Flares were detected during the second transit, bringing the total to 17. A pretty impressive run! Of course there was also the energetic M9.7 flare early Saturday morning which produced a bright CME that is expected to deliver a glancing blow to our geomagnetic field within the next 24 hours. The chances of surviving the trek around the farside yet again is likely much smaller, but we will see later this month. So long for now! https://solarham.com/pictures/2024/jun9_2024_3664.jpg View Quote |

I expected sunspots to decay before they could make more than a full rotation. I guess not now.

Despite shrinking in size, the region still remains potent as it turns behind the west limb. A coronal mass ejection (CME) is associated with the event and is heading to the west and away from Earth. Other than the radio blackout, no major impacts are expected. Perhaps in two weeks we will see whatever remains of the flare producing machine turn back into view once again. Bye for now!

June 10, 2024 @ 16:50 UTC (UPDATED)
The edge of the CME produced early Saturday morning by the M9.7 eruption just passed the ACE spacecraft. A passage past Earth is expected within the next 45 minutes. The solar wind speed increased by nearly 100 km/s to just over 400 km/s and the Bz component of the interplanetary magnetic field (IMF) is initially pointing south. More details to follow. CME Impact: The Boulder magnetometer detected a geomagnetic sudden impulse just after 17:20 UTC. This is the moment the expected CME passed Earth. Enhanced geomagnetic activity, possibly reaching storm levels will be possible for the remainder of today. SUMMARY: Geomagnetic Sudden Impulse Observed: 2024 Jun 10 1725 UTC Deviation: 52 nT Station: NGK |

Looks like we dodged a bullet back in May.
https://www.nasa.gov/solar-system/planets/mars/nasa-watches-mars-light-up-during-epic-solar-storm/ Lots of embedded pictures/movies at the link. In addition to producing auroras, a recent extreme storm provided more detail on how much radiation future astronauts could encounter on the Red Planet. Mars scientists have been anticipating epic solar storms ever since the Sun entered a period of peak activity earlier this year called solar maximum. Over the past month, NASA’s Mars rovers and orbiters have provided researchers with front-row seats to a series of solar flares and coronal mass ejections that have reached Mars — in some cases, even causing Martian auroras. This science bonanza has offered an unprecedented opportunity to study how such events unfold in deep space, as well as how much radiation exposure the first astronauts on Mars could encounter. The biggest event occurred on May 20 with a solar flare later estimated to be an X12 — X-class solar flares are the strongest of several types — based on data from the Solar Orbiter spacecraft, a joint mission between ESA (European Space Agency) and NASA. The flare sent out X-rays and gamma rays toward the Red Planet, while a subsequent coronal mass ejection launched charged particles. Moving at the speed of light, the X-rays and gamma rays from the flare arrived first, while the charged particles trailed slightly behind, reaching Mars in just tens of minutes. The unfolding space weather was closely tracked by analysts at the Moon to Mars Space Weather Analysis Office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, which flagged the possibility of incoming charged particles following the coronal mass ejection. If astronauts had been standing next to NASA’s Curiosity Mars rover at the time, they would have received a radiation dose of 8,100 micrograys — equivalent to 30 chest X-rays. While not deadly, it was the biggest surge measured by Curiosity’s Radiation Assessment Detector, or RAD, since the rover landed 12 years ago. RAD’s data will help scientists plan for the highest level of radiation exposure that might be encountered by astronauts, who could use on the Martian landscape for protection. “Cliffsides or lava tubes would provide additional shielding for an astronaut from such an event. In Mars orbit or deep space, the dose rate would be significantly more,” said RAD’s principal investigator, Don Hassler of Southwest Research Institute’s Solar System Science and Exploration Division in Boulder, Colorado. “I wouldn’t be surprised if this active region on the Sun continues to erupt, meaning even more solar storms at both Earth and Mars over the coming weeks.” During the May 20 event, so much energy from the storm struck the surface that black-and-white images from Curiosity’s navigation cameras danced with “snow” — white streaks and specks caused by charged particles hitting the cameras. Similarly, the star camera NASA’s 2001 Mars Odyssey orbiter uses for orientation was inundated with energy from solar particles, momentarily going out. (Odyssey has other ways to orient itself, and recovered the camera within an hour.) Even with the brief lapse in its star camera, the orbiter collected vital data on X-rays, gamma rays, and charged particles using its High-Energy Neutron Detector. This wasn’t Odyssey’s first brush with a solar flare: In 2003, solar particles from a solar flare that was ultimately estimated to be an X45 fried Odyssey’s radiation detector, which was designed to measure such events. Auroras Over Mars High above Curiosity, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) orbiter captured another effect of the recent solar activity: glowing auroras over the planet. The way these auroras occur is different than those seen on Earth. Our home planet is shielded from charged particles by a robust magnetic field, which normally limits auroras to regions near the poles. (Solar maximum is the reason behind the recent auroras seen as far south as Alabama.) Mars lost its internally generated magnetic field in the ancient past, so there’s no protection from the barrage of energetic particles. When charged particles hit the Martian atmosphere, it results in auroras that engulf the entire planet. During solar events, the Sun releases a wide range of energetic particles. Only the most energetic can reach the surface to be measured by RAD. Slightly less energetic particles, those that cause auroras, are sensed by MAVEN’s Solar Energetic Particle instrument. Scientists can use that instrument’s data to rebuild a timeline of each minute as the solar particles screamed past, meticulously teasing apart how the event evolved. “This was the largest solar energetic particle event that MAVEN has ever seen,” said MAVEN Space Weather Lead, Christina Lee of the University of California, Berkeley’s Space Sciences Laboratory. “There have been several solar events in past weeks, so we were seeing wave after wave of particles hitting Mars.” New Spacecraft to Mars The data coming in from NASA’s spacecraft won’t only help future planetary missions to the Red Planet. It’s contributing to a wealth of information being gathered by the agency’s other heliophysics missions, including Voyager, Parker Solar Probe, and the forthcoming ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission. Targeting a late-2024 launch, ESCAPADE’s twin small satellites will orbit Mars and observe space weather from a unique dual perspective that is more detailed than what MAVEN can currently measure alone. More About the Missions Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington. MAVEN’s principal investigator is based at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder. LASP is also responsible for managing science operations and public outreach and communications. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the MAVEN mission. Lockheed Martin Space built the spacecraft and is responsible for mission operations. NASA’s Jet Propulsion Laboratory in Southern California provides navigation and Deep Space Network support. The MAVEN team is preparing to celebrate the spacecraft’s 10th year at Mars in September 2024. |

As expected, the edge of a CME passed Earth on Monday, but the impact was fairly weak and did not generate a geomagnetic storm. As of this update, no other plasma clouds are expected to pass our planet so the geomagnetic field should return to quieter levels over the next few days. |

Protons blasted away from the Sun following this event are still finding their way past Earth, but the levels currently sit just below the minor (S1) radiation storm threshold. The source of the eruption was likely AR 3697 (3664). https://solarham.com/pictures/2024/jun12_2024_cme.jpg View Quote Large Farsided Coronal Mass Ejection (6/11/2024) - SolarHam.com |

One can only wonder if our old friend AR 3664 is up to old tricks again. https://solarham.com/pictures/2024/jun17_2024_cme.jpg View Quote Second CME: This is not a replay of my previous post from this morning, but a second coronal mass ejection (CME) is seen leaving the farside of the Sun around 11:00 UTC (Jun 17). This one appears to be more northerly directed, but again because it is farsided, it will be directed away from Earth. |

The Bz component of the interplanetary magnetic field (IMF) which is carried past Earth via the solar wind, has been pointing south the past few hours (-10nT). Active (Kp4) geomagnetic conditions will be likely with a chance for minor (G1) geomagnetic storming in the hours ahead. Aurora sky watchers at high latitudes should be alert should local light and weather conditions allow. WARNING: Geomagnetic K-index of 5 expected Valid From: 2024 Jun 28 0150 UTC Valid To: 2024 Jun 28 0600 UTC Warning Condition: Onset NOAA Scale: G1 - Minor |
