Solar Synoptic Map - An equatorial coronal hole could bring fast solar wind (450-600 km/s) on 6 or 7 March - 4 sunspot groups, quite simple without growth and low solar flare activity

Synoptic map of the sun - low solar flare activity - 5 rather simple sunspot groups on the visible disk; 4384 is showing development - negatively polarised coronal hole CH29- will cross the central meridian soon and could bring fast solar wind in 3-5 days

Sun: Polar crown filament lift-off The video is made with imagery of NASA's SDO satellite - reliable, high quality images of the sun used for science and operations. The White House wants to cut its budget now. We need SDO! Please don't cut the budget.

Increasing solar flare activity, partly caused by a new sunspot group behind the northeastern limb.

Solar Synoptic Map - central coronal holes have shrunk - new sunspot group in the east

Sunspots and solar flare activity (SDO AIA 171, 94)

Some activity near the eastern limb of the Sun…

50 hours – southeastern limb of the sun - active regions, coronal loops, solar flares – we'll see if they survive until they reach the earth-strike zone

Solar Synoptic Map - long, positively polarised coronal holes near the central meridian could bring moderately elevated solar wind speeds soon - new sunspot groups near the east limb of the sun end the spotless period

Some plasma ping pong on the sun could have produced an earth-directed CME

Flaring regions north and south of the solar equator are approaching the eastern limb of the Sun.

Synoptic map of the Sun Only three tiny sunspots left in a small unnumbered region near the centre of the visible disk. Coronal hole CH26– is dominating the earth's space weather with fast solar wind and aurora at high latitudes Two larger filament eruptions occurred near the SE and SW limb

Eastern limb of the sun: A large filament is lifting off

Western limb of the Sun: Filament eruption and some subsequent plasma rain… SDO AIA 171, 193, 131, 304Å

Possible CME impact - likely in association with a large streamer blowout to the southeast and a stealth CME from coronal hole CH26 opening to the west (?) a large halo from N to S visible in STEREO A COR2 and LASCO C2 - here the bundle in STEREO Heliospheric Imager, 18 Feb

3½ days of a 'quiet' sun - few sunspots, small flares but still coronal mass ejections everywhere: mainly streamer blowouts and filament eruptions.

Eruptive C-class flare from region 4377 near the central meridian of the sun. Waiting for coronagraphs to see whether we've got a little CME with possible earth-directed components

The sun with potential magnetic field (PFSS model) and coronal streamers

The butterfly or thyroid coronal hole has returned to its original size after being nibbled away at by sunspots on all sides. Current number is CH26, it could bring us some decent aurora shows soon, at least at higher latitudes…

Synoptic map of the Sun - Only small and simple sunspot groups - Many large filaments, will one of them lift off? - Waning influence of coronal hole CH24+ (decreasing solar wind speed) - CH26– is approaching central meridian and could bring fast solar wind in 2-4 days (– = favourable polarity now)

The sun is quiet, yet eruptions are occurring – and coronal hole 26 in the east has doubled in size. spacewx.org/sun-clears-up-fast-solar-wind-hardly-any-flares/

Streamer blowout CME and short eclipse caught by the CCOR-1 coronagraph. We can see that large parts of the southeastern corona have lifted off in SDO base difference imagery, far side and near side of the sun involved. The coronal mass ejection (CME) is large but slow (not earth-directed)

Fast solar storm launch from the far side behind the southwestern limb makes a filament (prominence) wiggle…

Polar Cap Index is getting high - 7 mV/m - Aurora likely in higher mid-latitudes

CME with possible earth-directed components from a filament eruption close to/ east of coronal hole CH24 near the centre of the sun. Waiting for model runs…

Eruptive M2.4 solar flare from behind the eastern limb of the sun. The lower part of the flare was obscured by the limb, so we may assume that the actual strength was much stronger. We can see a filament associated with an active region lifting off.

Solar Synoptic Map - no active regions in the south - only small, simple and stable regions in the north - low flare activity, low flare risk The large coronal hole CH24+ dominates the visible disc and the solar wind near earth with speeds between 600 and 700 km/s

In the solar wind we can see the stream interaction region that is preceding the fast solar wind from coronal hole CH24+ (high density, enhanced magnetic field), together with an ongoing sector boundary crossing (direction of the magnetic field towards/away from the sun flips = Phi -/+)…

Solar Synoptic Map Sunspot groups on the visible disc are small and simple with low flare activity. The most prominent feature is coronal hole CH24+. Its fast solar wind is expected to arrive 15 Feb or 16 Feb. … continue in comments section …

Now in English as well: My space weather forecasts and analyses - The latest post discusses the M1.1 flare from today (2026-02-13 0900z) spacewx.org/quiet-sun-oc...

M1.1 flare from (anemone) active region 4373 near the center of the sun. A coronal mass ejection with strong northward deflection was produced (800 km/s). There is a very small chance for a glancing blow in two days - depending on the arrival time of the high-speed stream from coronal hole CH24+.

Region 4366 bids farewell with an impulsive and a gradual M-class flare, neither of which appear to be eruptive (left). Meanwhile, a large filament is winding in the south (right).

Small filament eruption from region 4371 around 0000 UTC 10 February. A faint coronal mass ejection to the southwest is visible in the CCOR-1 coronagraph – data gaps in other coronagraphs at that time. Weak impact/ glancing blow possible in 2-4 days - high uncertainty

☀️ Complex sunspot group 4366 is leaving the visible disc Region 4374 near the E limb is showing C-class flare activity, largest C9.2 so far, playing with a filament Remaining regions decayed to simple unipolar groups/ spots Small coronal hole CH22 could bring slightly elevated solar wind soon

New active regions are approaching the eastern limb of the Sun. Let's see if they will cause significant space weather events...

Region 4366 has started producing M-class flares again. It is now connected to region 4358 behind the western limb. Some of the ejected material was hurled in this direction. 4366 is slowly moving away from Earth's strike zone and and earth-directed solar storms are becoming increasingly unlikely.

7 days of sunspot group 4366 – after a certain decay, it is now showing new flux emergence and growth. The leading spot has changed its direction of rotation. It is now rotating counterclockwise.

Solar Synoptic Map - Large and complex region 4366 has taken a break but is showing growth in its intermediate and trailing section again - Region 4362, N-S configuration, fired two M-class flares and a coronal mass ejection (CME) that may graze earth 8 February continue in the comment section

Another reabsorbed filament eruption near the Sun's west limb.

Filament activity in the southwest of the Sun.

M1.8 flare – sunspot group 4362 (magnetically connected to region 4366). A subsequent coronal wave is spreading S, as well as a CME – also pointing S in SOHO LASCO C2. If that CME is related (not from the far side) It might pass below Earth's orbit. I wouldn't rule out earth-directed components.

☀️ 5½ days of sunspot group 4366 ☀️ We've seen 63 M-class flares, 6 X-class flares, 0 radiation storms, 5 coronal mass ejections (CMEs) - 3 of them slow. It has passed its zenith, but it is not yet at an end. The big question is: will it produce another CME?

Following the strong X4.2 solar flare at 12:00 UTC, sunspot group 4366 has calmed down. It now looks more like a bipolar region, but the leading spot still shows remarkably fast rotation, which can lead to stress and possibly an eruption.

Now for something completely different: East limb of the sun with beautiful filament structures.

Strong solar flare with magnitude X4.2 from sunspot region 4366. We see opening field lines, dimming to the north, brightening, post-eruptive arcades - indicators that a coronal mass ejection (CME) left the corona. Coronagraphs show a faint loop CME that looks quite earth-directed.

24-hour development and flaring of sunspot region 4366 – more and more coronal loops and dense core filaments are appearing.

Sunspot group 4366: Magnetic flux emergence, magnetic shear, strong solar flares continue… 2026-02-03; 0200 - 1600 UTC

Current sunspot situation for large group 4366: Strong magnetic shear and rotation continue – potential for further strong flares (02.02. 16:00 UTC – 03.02. 02:00 UTC)

Just another video from the X8.1 flare on 2026-02-01 23:58z - We can see how a filament explodes and unfolds in the corona. The associated CME is expected to arrive/graze us late on February 4 or more likely early on February 5. Don't expect too much from it.

Development of sunspot group 4366. A complex 'bad actor' that produces many strong to very strong flares, but so far only one very slow coronal mass ejection. It mainly fires blanks. The animation shows the sun's photospheric magnetic field (the 'surface' field), sunspots and flares.
