The Sun’s only visible active region sputtered and spurted and eventually unleashed a small solar flare on Feb. 7, captured here by our Solar Dynamics Observatory satellite. The flare appears as a brief, bright flash about midway through the half-day-long clip. Normally, a flare this small might not catch much attention, but solar activity is increasingly rare as the Sun is slowly approaching solar minimum, a natural low point in its 11-year activity cycle. These images were taken in a wavelengt

🌞 Sun activity November 9, 2023: Dancing prominences, plus jets and filaments 🤩 Although sun activity is classified as low, we’ve seen faint flares and jets around the solar disk over the past day, as well as a long-lasting prominence on the north pole. It’s been dancing mesmerizingly all day long, right on the limb—we've found it hard to stop watching! 🫣 😮 Elsewhere, sunspot region AR3483 has been growing since its arrival yesterday and has maintained its explosive activity.

Solar Activity Report: November 17-23, 2025 Solar activity remained at low levels throughout the reporting period, predominantly within the B-class flare range. Four high-intensity C-class flares and several weaker C-class events were observed, with the largest—a C9.9—occurring on November 19 from a region just beyond the northeast limb. No Earth-directed CMEs were detected during this interval. The latest helioseismic far-side map indicates the presence of two active regions, both with a high p

What is the connection between Solar Activity and Space Weather? It starts with a dynamic Sun changing the space around it according to its magnetic cycle. As the current solar cycle #25 approaches its maximum, we are experiencing Space Weather events more often here on Earth.

🌞 👀 Sun activity for November 14, 2023 See a solar jet blasting sun-stuff into space 🤩 🌎 Over the past day, we saw beautiful active filaments all over the Earth-facing sun. 😱 And early this morning, we saw the solar jet extending from the sun’s outer atmosphere. This jet isn’t made of ordinary matter. It’s a collimated, beam-like ejection of what’s called plasma, a fourth state of matter consisting of elementary particles and magnetic fields from our blazingly hot star. 😎 🥳 It’s this sola

Solar Activity Report: December 22-28, 2025 Solar activity was low at the start of the week, with X‑ray flux generally confined to the low C‑class range aside from a few higher C‑class events. Activity increased markedly on December 27, highlighted by an M5.1 flare from active region 14325 at the east limb and a C9.9 flare from active region 14318 near the disk center. M‑class activity continued into December 28, when active region 14325 produced an impulsive M1.3 flare and active region 14317 g

🌞 📰 Sun news July 2, 2024: Is Solar Cycle 25 peaking? 😮 It is now official that the June sunspot number reached 164.2, which places last month in second place, slightly behind May 2024, which had the highest sunspot number of Solar Cycle 25, 171.7. 🤔 The current solar cycle quickly surpassed all expectations of its size and activity level. Over the past several months, we have seen historic geomagnetic storms and intense solar activity. Unfortunately, we have to wait a few months past a peak

🌞 📰 Solar superstorm is ongoing. More auroras tonight? 😱 WOW! Last night, there was an auroral explosion across the globe. The anticipated geomagnetic storm reached levels much higher than expected. But if you missed it, there’s a good chance for more tonight. 🤩 Overnight, the level of geomagnetic activity climbed to a G5 (extreme) storm. A series of coronal mass ejections (CMEs) arrived a bit earlier than anticipated, reaching us late yesterday, May 10. It appears that one or more CMEs over
