SOHO catches 3 new comets

The coronagraphs on board the SOHO spacecraft have discovered again a number of (small) comets. The Sun remained unharmed.

The Sun's farside joins the party!

Some dynamic and impressive prominence activity took place on the Sun's farside during 26-27 March. The associated CME was a lot less spectacular.

13-14 March: two geomagnetic storms compared

Last weekend, on 13 and 14 March, a minor geomagnetic storm took place. 32 years ago, on exactly the same days, geomagnetic activity was quite different...

A sunspot activity nest

NOAA 2806 emerged on 28 February, became spotless on 5 March, then re-emerged a day later.

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.

Quo vadis, European Space Weather community?

A group of European space weather actors proposes to open a discussion on the organisation and sustainability of the European Space Weather community and its assets in the (near) future.

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.
