The Sun is far more than just a steady source of light. It is a dynamic, magnetically active star whose influence reaches far beyond the boundaries of our planetary system. In this section, we focus on the study and observation of our central star and the complex processes that drive space weather.
We provide in-depth insights into the various layers and activities of the Sun:
Sunspots & Photosphere: Analysis of active regions (AR), where intense magnetic fields disrupt convection and create darker, cooler zones.
Flares & Prominences: Reports on high-energy eruptions and massive streams of matter ejected from the solar atmosphere into space.
Solar Corona & Space Weather: Learn how solar winds and coronal mass ejections (CME) interact with Earth’s magnetic field and trigger auroras.
By combining real-time observational data – such as our white-light captures in the archive – with scientific facts, we offer a comprehensive resource for every solar observer.
The Sun is the center of our planetary system. It provides light, heat, and energy, drives space weather, and has fascinated astronomers for millennia. But what lies beneath that glaring surface? The layers of the Sun are highly complex and…
[Live Update: Feb 5, 2026 – 7:15 AM CET] The CME impact has begun! A shock reached the L1 point yesterday afternoon, with solar wind speeds jumping past 400 km The Kp-index is currently rising through 4.33 (active). Despite poor…
Our closest star the sun is proving that it is far from quiet after the maximum of Solar Cycle 24 in late 2024. For those who monitor space weather, the last 48 hours have been nothing short of spectacular. A…
Overview of Magnetic Complexity The solar disk currently exhibits a significant concentration of magnetic activity centered around the combined active regions AR 4294, AR 4296, and AR 4298. This clustering of large sunspot groups represents a region of high magnetic…
Sunspots are the most visible manifestation of the Sun’s magnetic activity as darker, cooler regions on the solar surface that play a critical role in our understanding of the Sun’s variability and its impact on Earth. These fascinating phenomena are…
