Sterneruptionen im Labor: Erster experimenteller Nachweis für deren Unterdrückung durch starke Magnetfelder
"
".. Nachweis erbracht, dass starke Magnetfelder aktiver Sterne koronale Massenauswürfe vollständig unterdrücken können. .. erklärt, warum massereiche stellare Eruptionen bei Sternen viel seltener beobachtet werden als bei der Sonne. .."https://www.aip.de/de/news/stellar-eruptions-laboratory-experiment/

NASA's Parker Solar Probe Flew In And Out Of The Solar Corona And Found A Source Of High-Energy Particles That No Existing Model Had Predicted
(When NASA's Parker Solar Probe passed through the solar corona during perihelion encounters at the heliospheric current sheet, its instruments recorded energetic protons at energies far above what existing models of particle acceleration at that location could account for.)

“… A team… at the Southwest Research Institute… and… the University of Maryland’s Institute for Research in Electronics and Applied Physics has published an analysis of those measurements [link above]…, identifying magnetic reconnection at the heliospheric current sheet as the mechanism responsible. The proton energies detected were, in the study’s framing, approximately a thousand times greater than the available magnetic energy per particle that models of this process had predicted.
The finding matters for two reasons: it identifies a source of energetic particles close to the Sun that was not anticipated, and it raises questions about how far the existing understanding of reconnection-driven particle acceleration extends…
The Parker measurements suggest that picture needs revision. The magnetic island merging mechanism [the authors] identif[ied] can evidently produce proton populations at energies that challenge the boundary between what reconnection does and what shock acceleration does. Whether this source can explain a significant fraction of observed near-Earth energetic particle events, or whether it contributes mainly at energies and scales that remain confined close to the Sun, is a question the paper does not yet resolve…
Solar Orbiter, the European Space Agency mission operating in coordination with Parker, offers complementary measurements at somewhat greater distances. Comparing what the two spacecraft measure of the same particle populations as they propagate outward from the Sun will help establish which features originate close to the source and which are modified by the intervening solar wind. The energetic particle observations that puzzled researchers in the pre-Parker era now have a candidate mechanism. Whether that mechanism accounts for a large or small fraction of what actually reaches Earth remains the open question…”

Aurora Borealis To Light Up Earth As Solar Storm Intensifies; Will India Witness Northern Lights?

Auroras are... plausible this evening. If this wave of particles holds strong until after sunset. I will keep posting updates until dark.

A series of Coronal Mass Emissions (CMEs) ejected by the Sun during solar flares over a day and culminating in an X1.1 flare at about 1120Z 3Jun2026 have combined and are predicted to reach Earth at about 1900Z on 4Jun2026.
That's 7am NZ time so we'll probably miss the aurora which could be really rather strong, but if it is dark where you are then, look to the poles, and set up a static camera to take long exposures.

Several coronal mass ejections are expected to impact the Earth within the next 24-48 hours, possibly resulting in significant geomagnetic activity and visible auroras in far southern Victoria and Tasmania during local nighttime hours. Aurora alerts will follow if significant geomagnetic activity actually occurs.

Für die Nacht von heute 04.06.2026 auf morgen 05.06. Vorhersage eines G3-Sturms mit kurzen Phasen von G4 möglich - damit wären Polarlichter bis nach Österreich möglich.
Zeitlich ist das immer schwierig vorherzusagen, lt. aktuellen Prognosen ab etwa 0 Uhr UTC, also 2 Uhr Nachts unserer Zeit.
Edit: Sommerzeit = UTC + 2 h"UPDATE on G3 Watch for 4-5 June UTC Days"
https://www.swpc.noaa.gov/news/update-g3-watch-4-5-june-utc-days -
Also falls wer am 5. Juni klares Wetter hat (im Gegensatz zu hier 😭), sollte die Situation beobachten: mögliche Polarlichter in Mitteleuropa.
Heute gab es 3 Solar flares mit M9.3, M7.9 und X1 und damit zumindest zwei CME's. Derzeit wird mal von G3 gesprochen. Mal sehen.
Stay tuned.https://www.spaceweatherlive.com/de/sonnenaktivitat/sonneneruptionen.html

#SpaceWeather : #Sun ☀️ activity jumped to moderate over the past day, with 24 total flares. Three of them were M, or moderate flares, and one was edging up toward being an X flare
Forecast:
📆 April 4 we might get more G1-G2 (minor-moderate) #geomagnetic storms
📆 April 5 possibly with more G1 enhancements
📆 April 6 unsettled-to-active conditions as effects from the solar wind stream and #CME start to subsidehttps://earthsky.org/sun/sun-news-activity-solar-flare-cme-aurora-updates/

Unlike the easily predictable #radiation ☢️ exposures from flying through the Van Allen Belts or basking in the background flux of #galactic 🌌 cosmic rays, the dose an #astronaut gets from #solar ☀️ activity can vary enormously. Predicting #SpaceWeather remains a decidedly inexact 🔮 #science. High-energy #protons and #ions can tear through metal and flesh alike, damaging #DNA and other delicate cellular machinery. Typically, these showers are linked to #CME https://www.scientificamerican.com/article/space-weather-could-threaten-nasas-artemis-ii-astronauts-during-their-trip/

#SpaceWeather : The chance for strong flares ☀️ increased to 20%. The main driver is active region #AR4405
Forecast:
📆 April 1: A #CME may provoke enhancements up to G2 (moderate) geomagnetic storming late today
📆 April 2: G1 (minor) #geomagnetic storm levels expected
📆 April 3: Unsettled to active conditions may occur. A chance of G1 (minor) storm intervals exists if the next coronal hole’s fast solar wind stream arrives earlier than expected
