The NANOK expedition

Two Belgian adventurers collaborate with STCE scientists during an untypical triathlon in Greenland in April 2022: 600 km with skis and a pulka, 1000 km sea kayaking and 1 km vertical rock ascent. Nanok is a polar bear in the Inuit culture.

Two active regions, three CMEs

Two sunspot regions took care of this week's solar activity by producing three flares and associated CMEs.

One CME a day... keeps the SWx forecaster busy!

Solar activity is gradually increasing. From 20 till 23 February, there was 1 CME each day. Only the first one had an earth-directed component, the other CMEs were clearly directed away from Earth or farside events.

EUI 1 year in space

The extreme ultraviolet imager, EUI is 1 full year in space in its VIP seat behind the heath shield from where it peeks through a hole at the Sun. The EUI team worked hard to get down the coolest images ever.  

Delivery of SWx experts

Space Weather is 'in' and more and more organisations want to learn about it. They are right to do so.

Solar storms drop their energy in the Earth's magnetosphere and atmosphere and as such lie at the basis of space weather. Technology that relies on satellite navigation and radio wave propagation can be impacted by space weather, as well as large energy transport systems like electrical grids. Harmful radiation at flight altitude can increase when a solar storm hits Earth.  

A filament leaving the Sun

Late on 2 February, a filament near the northwestern solar limb became unstable and erupted. The associated CME was not directed to Earth.

Enhanced electron flux

Last week, in response to the high speed solar wind stream associated with a coronal hole, the level of energetic electrons in the Earth's magnetosphere increased significantly. Fortunately, this time, these "killer electrons" did not permanently phase out a satellite.


On 22 January, a bright fireball illuminated the morning skies of the Netherlands, Belgium, the United Kingdom and the north of France. BRAMS stations did not capture the radio signal of this fireball due to a particular set of circumstances.

NOAA 2786: Take 3!

As seen from Earth, old sunspot group NOAA 2786 has started its third transit of the solar disk.

PROBA2's view of the Sun

A poster with imagery by the PROBA2/SWAP instrument showing the evolution of the Sun's corona in 2020 has been released.
