During April and May 2025, the sun’s increased activity and dynamic changes across various wavelengths drew the attention of telescopes and cameras. A new sunspot, designated Active Region 4079, emerged on the eastern edge of the sun in late April 2025, following its previous circulation as No. 4055.
The detailed view captured on May 3, 2025, in white light, is a stack from a 37-second film recorded at 100 frames per second. A Baader solar filter OD 3.8 was used. The focal length was extended using eyepiece projection with a Tele vue Plössl F 21 mm eyepiece, according to Olaf Squarra.

Sunspot AR 4079: A Celestial Spectacle on May 3, 2025
What is Sunspot AR 4079?
Sunspot AR 4079 was a newly emerged sunspot, a region of intense magnetic activity on the Sun. It was observed in late April 2025 and was particularly visible on May 3, 2025.
Why is Sunspot AR 4079 engaging?
sunspots are interesting because they indicate areas of strong magnetic fields on the Sun’s surface. These regions can be precursors to solar flares and coronal mass ejections (CMEs), which can affect Earth. The emergence of a new sunspot, like AR 4079, always sparks interest among astronomers and solar observers who are studying the Sun’s dynamic changes.
When and where was the image of Sunspot AR 4079 taken?
The detailed view of Sunspot AR 4079 was captured on May 3, 2025, at 11:00 UT (Universal Time) in Rostock.
What equipment was used to capture the image of Sunspot AR 4079?
The image of Sunspot AR 4079 was captured using the following equipment:
- camera: Panasonic Lumix GH6
- Telescope/Lens: Pentax 125SDP, Tele Vue Plössl f 21 mm eyepiece, Baader Solarfolie OD 3.8 solar filter.
- Mount: Losmandy G11
What is a Baader Solar Filter and why is it used?
A Baader Solar Filter (in this case,OD 3.8) is a special filter that blocks the intense light and harmful radiation from the Sun, making it safe to observe and photograph the Sun. Without this filter, looking at the Sun through a telescope or camera lens can cause serious eye damage. The “OD 3.8” refers to the optical density of the filter, which determines how much light it blocks.
What does “eyepiece projection” mean in the context of this image?
Eyepiece projection is a technique used in astrophotography to increase the magnification of the image formed by a telescope. In this case, the Tele vue Plössl f 21 mm eyepiece was used in conjunction with the Pentax 125SDP telescope. This setup effectively magnifies the solar image to capture finer details, such as those found in sunspots.
What is the exposure time and ISO setting used for this image?
The image was captured with an exposure time of 1/1000″ (one-thousandth of a second) at an ISO setting of 100.
What post-processing techniques were used?
The image was processed using a “Planetary system stacker” and Apple Preview. Stacking involves combining multiple frames from a video to reduce noise and increase detail. apple Preview was likely then used for additional minor adjustments to the image.
