Topical Issue on "Space Climate" for JSWSC

JSWSC has opened a new Topical Issue "Space Climate: Long-term effects of solar variability on the Earth's environment".

Close-up of the Sun

The ESA-led Solar Orbiter mission has experienced its second close encounter with the Sun. It is delivering more stunning data, and at higher resolution than ever before!

Gamma Ray Burst!

A strong gamma ray burst affected the Very Low Frequency (VLF) radio communications on 9 October.

Fun with the Sun!

On 25 October, a partial solar eclipse will be visible from most of Europe, northeast Africa, the Middle East and the western portion of Asia. The eclipse can be followed live at the ROB/USET and PROBA2 websites, which provide also additional explanations.

And so they meet again…

EUI perihelion

Solar Orbiter speeds towards its next rendezvous with the Sun on the evening of October 12.

Latest news on SC25

The STCE's SC25 Tracking page has been updated to reflect the latest evolution in some critical space weather parameters for the ongoing solar cycle 25 (SC25).

Whodunit

On 1 and 2 October, the Sun produced an M5, an M8 and an X1 flare. The source was not the large and complex active region NOAA 3112, but the much smaller and somewhat simpler NOAA 3110.

Promises, promises!...

In white light, NOAA 13105 and 13107 looked like rather big and complex sunspot groups when they rounded the solar limb, but flare-wise they were quite a disappointment.

Come to ROB to study EUV brightenings with EUI!

The Royal Observatory of Belgium hires a full-time scientific collaborator, who will play a central role in ROB’s research on campfires.

Flashback

On 23 July 2022, 10 years after the Carrington-like event that happened on the same day, the Sun produced another quite strong event - again on its farside. Imagery by the Solar Orbiter has now revealed that the source was an erupting filament.
