Currently, there are more than 30.000 tracked objects moving in a Low Earth Orbit. More than half are space debris and may pose a threat to the operational satellites and payloads.

SIDC Sunspot Group 825 (NOAA Active Region 4419) was the source of 2 X-class flares produced on 24 April. The analysis of the associated CMEs is ongoing.

GONG, the Global Oscillation Network Group, is celebrating its 30 years of providing high-quality helioseismic and magnetic data for the benefit of solar physics and space weather research.

The Belgian-led ASPIICS coronagraph aboard ESA’s Proba-3 mission reveals a dynamic birthplace of the solar wind. Observations made by the ASPIICS coronagraph reveal a world of small-scale activity in the Sun’s inner corona, according to a new study led by the Royal Observatory of Belgium.

Two earth-directed coronal mass ejections surprised space weather forecasters with their arrival time and geomagnetic impact. The first one passed almost unnoticeable, the second one eventually resulted in a strong geomagnetic storm.

NOAA 4405 produced an X-class flare early on 30 March. The associated CME arrived around noon on 1 April. There's no chance on aurora over Belgium tonight. ***(UPDATED 2)***

Though the solar cycle maximum is already 1.5 years behind us, we may still expect a number of very strong solar flares over the next 2 years.

The STCE's SC25 Tracking page has been updated to reflect the latest evolution of some critical space weather parameters for the ongoing solar cycle 25 (SC25). Some significant space weather events have been recorded during the last five months.

The Sun was nearly spotless during a few days late February, as reported by SILSO (provisional sunspot numbers). The last spotless day dates back to 11 December 2021.
