Fast news - fast news

On April 23, 17:00 Universal Time, a magnetic cloud coming from the sun reached the earth. The STCE alert system started ringing the entire night and longer. 
For our PECASUS services for civil aviation, scientists and operators  in Belgium and Finland were continuously in contact to give a correct interpretation of the data which was coming in. 

An estimate of arrival

First eclipse of the year observed by PROBA2

In the early hours of April 20 a solar eclipse took place. Regions on Earth that saw, at least, a partial eclipse include parts of South/East Asia, Australia, and Antarctica. This meant that only a very small fraction of the world's population was able to witness this event. Even if it was a difficult eclipse to observe from the ground, PROBA2 had a front-row seat! 

JUICE en route to Jupiter!

On 14 April, ESA's Jupiter Icy Moons Explorer (JUICE) was launched on an 8 years journey to Jupiter to study the giant gas planet and its three large ocean-bearing moons.

Ionospheric storm!

Following the severe geomagnetic storm of 23-24 March 2023, the positive annd negative phases of the associated ionospheric storm as well as the related space weather effects were clearly observed.

New type of oscillations discovered on the sun (EN - NL - FR)

The Extreme Ultraviolet Imager aboard Solar Orbiter was able to observe magnetic loops that shake back and forth very quickly. Scientists suspect that it is these movements that heat the environment around the sun to millions of degrees Celsius.

Trouble near the southwest limb

A number of eruptions occurred on 29-30 March and 1 April near the southwest solar limb.

Severe geomagnetic storm!

A severe geomagnetic storm was recorded on 23-24 March.

Unexpected X-class flare

An X1.2 flare erupted from active region NOAA 3256 early on 29 March.

Rush to the Poles

Solar prominences are migrating towards the solar poles, heralding the reversal of the polar magnetic fields within 1 or 2 years.
