First Solar Orbiter/EUI Guest Investigator Call is now open

The EUI PI team welcomes research proposals for the first round of its Guest Investigator Program for research based on EUI and Solar Orbiter data analysis by scientists outside the EUI PI team.

Great news from PROBA-3/ASPIICS!

ROB/SIDC has successfully passed the Flight Acceptance Review of its Science Operations Centre for PROBA-3/ASPIICS

Déjà-vu all over? Not quite.

NOAA 3014 has been the largest sunspot group of the ongoing solar cycle so far, but despite its magnetic complexity, it has remained an underachiever in flaring activity.

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.


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


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.
