Sun news for February 7 – February 8. Now, 2 coronal holes on the Earth-facing sun
(11 UTC to 11 UTC)
And then there were two! A new, large coronal hole has formed in the sun’s southeast quadrant. And we’ve been observing another one during the past week, which has moved into geoeffective position, that is, a position where it’s capable of affecting Earth. Especially, coronal holes play an important role in space weather, the conditions in near-Earth space (especially electromagnetic radiation and charged particles emitted by the sun) that can affect human technologies. For instance, fast solar wind from coronal holes can provoke disturbances in Earth’s geomagnetic field, sometimes spawning auroral displays. Therefore, when combined with incoming blobs of solar material (CMEs) the results can be dramatic … as with the huge geomagnetic storm back in May 2024 and the one in October 2024.
Sun-Earth highlights in the past day
- Flare activity deja vu! Just like yesterday and the day before, as we write this article, the sun has produced an M flare to keep solar activity at moderate over the past 24 hours. The blast was an M2.1 produced at 9:27 UTC on February 8. The week’s lead flare producer – sunspot region AR3981 – produced it. Again today, AR3981 remains the leader. And this time, it produced eight flares, the mentioned M plus seven C flares. The M flare by AR3981 provoked an R1 (minor) radio blackout that affected an area over Madagascar.
- The total number of flares in the past day was 15, including one M flares and 14 C flares.
- There are 10 active regions on the sun’s Earth-facing side. A new sunspot, AR3988, emerged in the southwest quadrant, near the intersection point of the central meridian and solar equator.
- Active region AR3981 lost its delta and today it shows a beta-gamma magnetic configuration. But, it remains the largest region on the solar disk as seen from Earth. Soon to depart AR3981 is approaching the west limb (edge). AR3978 continues to display a beta-gamma configuration. The rest of the labeled active regions show either alpha or beta.
- Blasts from the sun: No coronal mass ejections (CMEs) struck Earth in the past day.
- Solar wind remained at normal levels over the past day. Solar wind speed remains steady this time at 353 km/s (219 miles per second) as of 11 UTC on February 8.
- Geomagnetic activity: The interplanetary magnetic field (a critical factor in creating auroras) was mostly quiet at Kp = 1-2 over the past 24 hours. But, it suddenly went up to active levels (Kp = 4) in the couple of three-hour periods previous to this report.
What’s ahead? Sun-Earth forecast
- Moderate solar activity is expected over the next 24 hours. The chance of M flares is 70%. Furthermore, the chance for X flares is at 25% today.
- Blasts from the sun? None of the M flares produced by AR3981 were detected with a component of the solar stuff coming our way at Earth. And no other coronal mass ejection (CME) is headed toward Earth at this time.
- Geomagnetic activity forecast: Quiet-to-unsettled geomagnetic conditions are expected on February 8 as Earth’s magnetic field may be reached by a glancing blow from a coronal mass ejection (CME) hurled into space by the sun on February 2 extended through tomorrow.


Sun news for February 6 – February 7. Check out this image from GOES-19!
(11 UTC to 11 UTC)
The Space Weather Prediction Center (SWPC) in Boulder, Colorado, unveiled preliminary test images yesterday from the new GOES-19 satellite’s CCOR-1 instrument (the Compact Coronagraph, which uses an occulting disk to help capture white light imagery of the sun’s corona or outer atmosphere). GOES-19 launched in June, 2024. It’s been in its shakedown phase. The new images resemble those captured by SOHO’s LASCO C-3 imager, which has been operational since its launch in 1995. SWPC and NOAA plan to begin a regular series of operational images from GOES-19 – the ones that’ll be used by scientists – in April 2025. Scientists can’t wait! And neither can we. Meanwhile, on the sun itself, activity remains high. Read more below.
Sun-Earth highlights in the past day
- Flare activity remained at high levels over the past 24 hours. An M7.6 flare from AR3981 contributed to the heightened activity. The flare erupted at 9:21 UTC on February 7, triggering an R2 (moderate) radio blackout over the southwestern coast of Africa. AR3981 remains the most active region on the sun’s Earth-facing side. It produced 12 flares in the past day: three M (moderate) flares and nine C (common) flares.
- The total number of flares in the past day was 21, including five M flares and 16 C flares.
- There are 10 active regions on the sun’s Earth-facing side. Furthermore, a new sunspot, AR3987, has emerged on the southeast limb near the solar equator.
- Active region AR3981 retains its beta-gamma-delta configuration and remains the largest region on the solar disk as seen from Earth. But, AR3977 lost its gamma-delta and today shows a beta configuration. AR3978 continues to display a beta-gamma configuration while the rest of the labeled active regions show either alpha or beta.
- Blasts from the sun: No coronal mass ejections (CMEs) struck Earth in the past day.
- Solar wind remained at normal levels over the past day. Solar wind speed remains steady at 438 km/s (272 miles per second) as of 11 UTC on February 7.
- Geomagnetic activity: The interplanetary magnetic field (a critical factor in creating auroras) was mostly quiet at Kp = 1-2 over the past 24 hours.
Sun news for February 5 – February 6. Use eclipse glasses for sunspot region AR3981
(11 UTC to 11 UTC)
As it’s crossed the sun’s Earth-facing disk this week, AR3981 has been living up to its potential. It produced an M7.5 flare this morning. That’s just shy of the X-class threshold! This high activity aligns with expectations given this region’s magnetic and physical complexity. And this region is big. Grab your eclipse glasses for safe solar viewing if you want to see it with your own eyes. Yes, AR3981 is large enough to be visible from Earth without magnification. But AR3981 isn’t alone on the Earth-facing solar disk in its potential. AR3977 now also exhibits a beta-gamma-delta magnetic configuration. Though not as large as AR3981, AR3977 – part of the quintet of sunspot regions (AR3976, AR3977, AR3978, AR3981, and AR3984) – is becoming increasingly active. Overall, space weather analysts have increased the probability of X-class flares in the coming day from 20% to 25%. That’s a high potential. Stay tuned for more excitement.

Sun news for February 4 – February 5: All eyes remain on AR3981
(11 UTC to 11 UTC)
Potent sunspot region AR3981 remains the one to watch on the sun. Even though its flare productivity decreased over the past day, and its growth slowed noticeably, there are more reasons to be excited about this region. Not only has AR3981 maintained its high-potential beta-gamma-delta magnetic configuration, but its delta region shows signs of what’s called shearing. That means its opposite magnetic polarities are moving in opposite directions, increasing the overall complexity and potential energy of the sunspot region. In simple terms, AR3981 is becoming more prone to sudden releases of energy, aka flares. Stay tuned, as this region could bring excitement at any minute.
Sun-Earth highlights in the past day
- Flare activity decreased to moderate levels over the past 24 hours. Flare productivity also decreased from 25 in the previous period to 13 in the past day: four M (moderate) flares and nine C (common) flares.
- The largest flare was an M4.7 at 11:09 UTC on February 4 from AR3981. It caused an R1 (minor) radio blackout over Madagascar.
- Sunspots: There are 10 active regions on the sun’s Earth-facing side. There are three newcomers: AR3983, AR3984 and AR3985. AR3981 remains the most active.
- Blasts from the sun: No coronal mass ejections (CMEs) struck Earth in the past day.
- Solar wind: Solar wind has been at normal levels in the past 24 hours, ranging from 400 km/s to 450 km/s (248 to 280 miles per second).
- Geomagnetic activity: The interplanetary magnetic field (a critical factor in creating auroras) was quiet (Kp = 0-1) over the past 24 hours.



Sun news for February 3 – February 4: Meet growing sunspot region AR3981
(11 UTC to 11 UTC)
Meet sunspot region AR3981! Activity remains high thanks to this region, which is now the largest and most complex of the eight sunspot groups on our star’s Earth-facing side. AR3981 has produced the most flares, and the biggest flares, over the past two days. As it moves closer to the center of the sun’s Earth-facing disk, its potential to affect Earth via the launch of blobs of solar materials and magnetic fields (aka CMEs) will rise. It hasn’t sent anything our way … yet. AR3981 first appeared on the solar disk on January 30, emerging in the sun’s northeast quadrant. It started with a simple alpha magnetic configuration, but rapidly grew to beta, soon gaining even more complexity. It now has a beta-gamma-delta magnetic complexity, signaling the capacity for large M flares and even X flares. Keep an eye on this sunspot region!
Sun-Earth highlights in the past day
- Flare activity remained high over the past 24 hours. And flare productivity increased slightly, from 23 to 25: seven M (moderate) flares and 18 C (common) flares.
- The largest flare was an M6.1 at 13:18 UTC on February 3 from AR3981. It caused an R2 (moderate) radio blackout over the South Atlantic Ocean.
- Sunspots: There are eight active regions on the sun’s Earth-facing side, with AR3981 the most active.
- Blasts from the sun: No coronal mass ejections (CMEs) have struck Earth in the past day.
- Solar wind: Solar wind from a large coronal hole is beginning to wane from 550 km/s to 450 km/s (340 to 280 miles per second) in the past 24 hours.
- Geomagnetic activity: The interplanetary magnetic field (a critical factor in creating auroras) was quiet (Kp = 0-1) over the past 24 hours.


Sun news for February 2 – February 3
(11 UTC to 11 UTC)
Sun activity has jumped to high after 12 M flares were fired over the past day, all of them from the same sunspot region! The prolific region, AR3981, has developed a high-potential beta-gamma-delta magnetic complexity, which is a sign that a region has the capacity for large M flares and even X flares. And, indeed, AR3981 came close to producing an X flare around 4 UTC this morning, blasting out an M8.8 flare (the X flare threshold is crossed at the equivalent of M10). This is definitely the region to watch!
Sun-Earth highlights in the past day
