A cluster of active regions behind the northeast limb of the sun is producing CMEs ('solar storms') - ex region 4419 is part of it - it produced two major X-class flares and several CMEs near and behind the western limb.

Solar Synoptic Map - low risk of major solar flares - relatively low sunspot dynamic (no significant flux emergence) - fast wind from coronal hole CH50+ will likely arrive 7 May (but its positive polarity is not very geoeffective in May)

Aurora: Red rays near Berlin, Germany

Pretty CME ('solar storm') from a filament eruption + plasma from the high corona near the east limb of the sun (not earth-directed)

Aurora oval currently south of 65°N over northern Europe - good chances to see red rays down to 50°N (or in the Alps) sesolstorm.kartverket.no/moreplots.xh...

The CME ('solar storm') from April 30 has likely arrived. Interplanetary magnetic field is favourably oriented southwards between -11nT and -8 nT. Aurora is currently visible on Russian webcams down to 54°N starvisor.net

Eruption of an active region filament near the west limb of the sun.

A large filament is currently attempting to break away from the Sun – if it does lift off successfully, this could lead to a CME (‘solar storm’) that might be directed towards Earth. We’ll see…

☀️ Choreographed double (triple) eruption ☀️

Estimated sunspot number: 159; 10 active regions on the visible disc – however, the sun has decided to remain quiet

Two slow CMEs were released from the vicinity of region 4228 in the southern centre of the visible solar disc. They may graze the earth around 5 May and possibly arrive together with the stream interaction region of the positively polarised coronal hole in the east〈

Aurora at higher mid-latitudes over Northern Europe (now)

Stream Interaction Region of coronal hole 48– has arrived, together with a glancing CME. New regions are emerging on the sun's far side ☞ spacewx.org/relatively-many-sunspots-and-yet-relatively-little-activity

Current active regions on the sun, most interesting a newly developing cluster in the southeast↙︎ Order of ARs: 4425, 4424, 4420, 4423, 4428, NEW

Solar Synoptic Map - Risk for M-class flares has decreased, all active regions have remained quiet over the past 24 hours - New region near the southeastern ↙︎ limb - 4428, 4420 and 4424 are growing (flux is emerging) but their complexity is limited at the moment

Solar Synoptic Map - High risk of M-class flares remains, mainly from 4420 and 4425 - New region in the south with a tendency to build up complexity (4428) - We should see the effects of coronal hole 48's stream interaction region soon (UNSETTLED - MINOR STORM levels possible)

Strong M6.0 solar flare from region 4420 near the solar centre. Visible ejecta, a circular coronal wave and radio emissions are indicative of a CME, possibly earth-directed. We have to wait for coronagraphs to confirm this.

Solar Synoptic Map: High M-class flare potential of regions 4425 and 4420; weak influence from + coronal holes CH45 and 47; negative CH48 influence from 29 April spacewx.org/m-class-flar...

X-flare producer 4419 has left the visible solar disc, 3-4 active regions with flare and CME potential remain - Eye-candy videos, synoptics and forecast: spacewx.org/m-class-flar...

Strong X2.5 flare from sunspot group 4419 with a huge plume of plasma heading towards northwest↗︎ and a coronal wave spreading towards the centre, where it is blocked by the central coronal hole.

Double eruption from region 4419 in the NW↗︎ (filament, strong N-ward deflection) and the vicinity of 4420 in the NE↖︎ of the sun. At least 3 CMEs are visible in coronagraphs. The one from 4420 might glance earth. Waiting for more data.

☀️ Synoptic Map - ongoing influence of coronal hole 42: elevated solar wind speeds ≈ 550 km/s, mainly S-ward magnetic field, occasional substorms - 4419: simplified; mainly inactive - NEW region SE of 4419 C-class flares from - 4420: rapidly growing in the NE, 1 CME - 4421: emerged on the far side

New flaring region is approaching the southeastern limb of the sun

Solar NE: New sunspot group with rapid development and mixed polarities (γ), connection with a filament behind the limb 🍿

New active region behind the southeast limb (an 'anemone' inside a coronal hole) - new flux/ sunspot emergence today – looks complex [SDO AIA, HMI + Solar Orbiter PHI, FDT]

Region 4419 is still alive - new spots of opposite polarity in the trailing section - one of them could count as a delta spot - It remains to be seen whether any magnetic stress will build up

A glance at the sun's far side with Solar Orbiter – not that much of development

Filament eruption – the coronal mass ejection will likely miss us (SDO, GOES, SOHO imagery)

Restructuring of the sun's corona is still ongoing - the coronal hole landscape is changing – the northern polar coronal hole has opened up again, a possible sign of increasing solar activity

Fast solar wind, a lot of coronal activity and coronal mass ejections in the mix could lead to mid-latitude aurora in the coming days (uncertain). Increasing chances for M-class flares spacewx.org/signs-of-lif...

The sun is shedding helicity

Filament eruption west of the southern edge of coronal hole 42. The corresponding CME appears initially slow (streamer blowout) but could be accelerated later. It probably has earth-directed components.

Sunspot group 4419 is whipping up the surrounding coronal hole with a filament.

Sunspot group 4419 appears to be growing and is doing things.

Solar Synoptic Map - 4416 has remained simply bipolar, thus inactive; signs of decay - 4419 is new and causing some turbulences in the corona, however magnetically rather simple - Trans-equatorial coronal hole 42 is large – potential to cause significant space weather in the coming days

Solar Synoptic Map Coronal hole CH38+ is sending us fast solar wind but its positive polarity makes it less geoeffective at this time of year. Region 4416 is new and has the potential to become a big flare player. We'll watch it closely.

Solar Synoptic Map Old regions in the west, new regions in the east, equatorial coronal hole in the middle – the arrival of its stream interaction region and subsequently of its fast solar wind is expected today, 9 April We watch closely that large filament in the southeast (possibly unstable)

Increasing solar activity: a large trans-equatorial loop near the eastern limb, filament eruptions near the eastern limb, slow eruption near the southwestern limb, large and fast eruption behind the NW limb – none of them directed towards the earth

A filament eruption near the eastern limb of the sun makes coronal loops wobble

Solar Synoptic Map - New region west of 4408 - New region approaching the east limb - Region 4405: only two spots left Fast wind of coronal hole CH38+ may arrive 9 April

Solar Synoptic Map 4405: remained silent 4409: signs of decay and reduced flare activity, but new flux is emerging and shear is increasing again 4412: new but simply bipolar Decreasing influence of C.H. 36 Fast wind of fragmented trans-equatorial + coronal hole in the E may arrive in a few days

'E's off the twig! 'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisible!! THIS IS AN EX-COMET!!

4 days of sunspot group 4409 Solar Flares: a lot Coronal Mass Ejections: one small & slow CME

Mauna Loa Solar Observatory has reopened - This animation shows images from the COSMO K-coronagraph combined with NASA's SDO satellite (AIA 211) (2026-04-01 2200z - 2026-04-02 0100z) mlso.hao.ucar.edu/mlso_data_su...

Strong M7.55 solar flare from sunspot group 4409. A core filament was disrupted. Minor dimming only, some opening field lines and only very few post-eruptive arcades indicate that not much material left the corona.

3 days evolution of sunspot region 4409 - now βγδ, with strong magnetic shear in the leading section and a complex sigmoid structure. At 2026-04-04 01:17 UTC it produced a solar flare of magnitude M7.55 (strong) and a strong microwave radioburst.

Solar Synoptic Map 4405 kept silent 4409 has a delta spot now, high flare risk Many filaments around active regions with high potential to erupt A filament eruption yesterday opened up the northern polar coronal hole. With both polar coronal holes present we can expect increased solar activity

Two large filament eruptions, the first one was partially reabsorbed - the second one has produced a decent CME - maybe with earth-directed components but the high-speed stream from the central coronal hole will likely block it.

Another filament lift-off. This time from the vicinity of region 4403 in the north of the sun.
