Current Sunspot and Flare Activity
The Sun currently displays 161 active sunspot regions visible from Earth, varying in size and magnetic complexity. No new regions detected in the past 24 hours.The largest sunspot is AR 4513, classified as Ekc, covering 310 millionths of the solar hemisphere (MSH), and containing 21 individual spots.
No significant flares detected today. Data current as of 29 June 2026 at 05:01.
Real-Time Solar Imaging
The data used in these images are provided by the Solar Dynamics Observatory (SDO), a NASA mission that studies solar variability and its effects on Earth. Its AIA and HMI instruments provide high-resolution, real-time images in multiple wavelengths for studying solar activity and space weather. We thank the SDO team and NASA for making these data publicly available.
Magnetogram
HMI magnetograms show the strength and direction of the magnetic field on the solar surface. Images from the HMI instrument aboard the Solar Dynamics Observatory (SDO) reveal complex magnetic structures, sunspots and active regions.
Intensitygram
HMI intensitygrams show the solar surface in visible light, highlighting sunspots, granulation and solar faculae. They provide a detailed view of the photosphere and make it possible to follow sunspot development and movement.
Solar Magnetism: Coronal Loop Dynamics
These 171 Å images highlight the solar corona and upper transition region. AIA images from the Solar Dynamics Observatory (SDO) reveal the outer atmosphere and its magnetic field lines, especially the million-degree plasma loops above the solar surface.
Active Regions, Flares and Coronal Holes
AIA 193 Å images show the hot corona, active regions, solar flares and coronal holes. This wavelength is especially useful for observing high-temperature plasma and regions where the solar wind escapes into space.
