The northern lights may be visible in Mass. Sunday night
The northern lights may be visible in Massachusetts Sunday night, according to the National Oceanic and Atmospheric Administration (NOAA). NOAA's aurora borealis predictor puts much of the Bay State below the view line for the natural light show Sunday night, which indicates the southern-most location from which the northern lights may be seen in the northern part of the sky. The aurora borealis may be visible in Massachusetts Sunday night because active geomagnetic conditions may push auroras farther south than usual, according to 'Space weather forecasters are forecasting strong (G3) geomagnetic storm conditions with the possibility of severe (G4) conditions thanks to both elevated solar winds and an Earth-directed coronal mass ejection (CME),' the astronomy news website reported Saturday. The skies over Massachusetts are predicted to be mostly clear Sunday night, according to the National Weather Service. recommends 1 a.m. to 2 a.m. as the best window for viewing the northern lights. 'But remember, auroras are fickle — sometimes they appear much farther south than predicted, and other times they barely show up at all. Many conditions have to align for the perfect display," the astronomy news website reported.

Powerful Solar Flare Sparks Geomagnetic Storms, Auroras Likely In Southern Skies
Positioned near the centre of the Earth-facing solar disc, this flare was accompanied by a major, asymmetrical full halo coronal mass ejection (CME). Earth was hit by a powerful geomagnetic storm on Sunday, June 1, with a speed of upwards of 1000 km/sec later. According to Space Weather Live, sunspot region 4100 produced a beautiful, long-duration M8.2-class solar flare, which peaked at 05:35 IST today (00:05 UTC). Located near the center of the Earth-facing solar disk, this flare is particularly significant. The eruption is associated with a Type II radio emission, indicating a coronal mass ejection (CME) was launched and current coronagraph imagery suggests it likely has an Earth-directed component. Positioned near the centre of the Earth-facing solar disc, this flare was accompanied by a major, asymmetrical full halo coronal mass ejection (CME), clearly visible in SOHO/LASCO imagery. This CME is all but certain to have an Earth-directed component, setting the stage for possible space weather impacts, including auroras, radio disturbances, and power grid fluctuations in higher latitudes. According to Space Weather Live, a minor G1-class geomagnetic storm was observed today, 1 June 2025, as the Kp index reached Level 5 — the threshold for a G1 storm — at 09:24 UTC, which is 14:54 IST. advetisement There is a slight possibility of auroral activity becoming visible in mid-latitude regions of the Southern Hemisphere, particularly around Hobart, Australia, and Invercargill, New Zealand, reported Space Live Weather. This potential is driven by highly active solar wind conditions, with the solar wind speed currently measured at an exceptionally high 1,023 km/sec. Additionally, the interplanetary magnetic field (IMF) strength is elevated at 25.55 nT. However, the IMF is currently pointing northward (6.11 nT), which typically reduces the chance of strong geomagnetic activity since a southward IMF is more favourable for coupling with Earth's magnetic field. While auroral visibility remains limited for now, even a brief southward shift in the IMF could quickly increase activity, making it worth monitoring if you're located in or near these regions.

Sun just unleashed a 10,00,000-km-long mega eruption. Will Earth be hit?
In what could only be described as a fiery burp, the Sun unleashed a mega explosion from its northern hemisphere hurtling millions of tons of solar material into solar filament caught by aurora chaser Vincent Ledvina, stretches over a million kilometres in length as it begins its journey away from the Sun.A solar filament is a large, elongated structure of cool, dense plasma suspended above the Sun's surface by magnetic fields. Despite being cooler than the surrounding solar atmosphere (the corona), it still emits light but appears dark when viewed against the bright background of the Sun. advertisement Solar filaments form along areas where the Sun's magnetic field is particularly the video on X, Vincent Ledvina wrote "Not sure what to call this eruption, maybe the "bird-wing" or "angel-wing" event? Either way, it is truly something to witness!"After weeks of relative quiet, the Sun has sprung back to life, unleashing two powerful solar flares from opposite first, an X1.2-class flare, erupted with force, causing a brief shortwave radio blackout over the Americas and launching a coronal mass ejection (CME) into space. According to NASA models, the CME is expected to strike Mercury, graze Venus, and miss Earth entirely later this a spectacular CME from the huge filament eruption earlier today! Unfortunately it is directed north and will miss us. A direct hit from a CME like this can be high-end G4 storm material, maybe even G5. Jure Atanackov (@JAtanackov) May 13, 2025advertisementThe second flare, rated M5.3, triggered a longer radio blackout across Southeast Asia and likely released a CME as well. If confirmed, this one may contain an Earth-directed component, but scientists await updated imagery from SOHO coronagraphs to verify its explosion comes over a year after the most severe geomagnetic storm in two decades struck Earth and triggered cascading effects on Earth's thermosphere, Earth's upper atmospheric layer was heated to a record 1,150C from the storm, causing it to expand and loft heavy nitrogen particles storm generated the largest electrical currents in Earth's magnetosphere in 20 years, which were observed by Nasa's MMS and THEMIS-ARTEMIS missions.
