EUI causes a revolution in solar physics (EN - FR - NL)

On March 26, 2022, the Solar Orbiter satellite came closer to the Sun than ever before. The images of this closest approach taken by the Extreme Ultraviolet Imager on board will revolutionize solar physics! 

A complex eruption in a small sunspot region

Last week's X-class flare showed a complex evolution in its soft x-ray emission.

An X-class surprise

NOAA 3006 is a rather small sunspot region, that has just produced an X1.5 flare at 13:55UT today. It concerns the same region that was also responsible for the X1 flare from 3 May.

ASGARD-XI

From 27 till 29 April, the 11th installment of the ASGARD project took place on the premises of the Planetarium and the Space Pole. About 80 students from Belgium, Spain and the United Kingdom came together for 3 days to participate in this educational space project.

X1.1 flare!

An X1.1 flare was observed on 3 May at 13:25UT. It originated from a region near the southeast solar limb.

A curious proton flux enhancement

A small enhancement in the proton flux observed on 29 April was most likely the result from a filament eruption in the spotless active region NOAA 2996.

X-class flare

NOAA 2994 produced an X-class flare while already behind the Sun's northwest limb

Lookalikes

The sunspot complex NOAA 12993-12994 has a very peculiar outlook quite different from other sunspot groups. Only a handful of lookalikes have been observed over the last few solar cycles.

Another X-class flare!

The strongest X-class flare so far this solar cycle was produced early on 20 April. The source of the eruption was behind the southwest solar limb, and not related to activity in the NOAA 2993/2994 sunspot complex in the northeast quadrant.

Hello, I'm back!...

A flare-active sunspot region that rounded the solar west limb 2 weeks ago is about to rotate onto the earth-facing solar hemisphere. During its previous transit, it was the source of numerous M-class flares and produced also an X-class event on 30 March. UPDATE 2: X-class flare!
