Teepee Prominence on the Sun | March 21, 2026
Philip Whitebloom
Captured in Elkridge, Maryland, USA.
This hydrogen-alpha view captures a dramatic section of the solar limb, highlighted by a striking teepee-shaped prominence extending outward around the 3 o’clock position.
The prominence rises in a triangular, teepee-like formation, with multiple layered arcs of plasma climbing above the limb and subtly curving back toward the Sun. Its structure reflects a complex magnetic configuration, where charged solar material is suspended and guided by magnetic field lines. The brightest regions are concentrated near the base, fading gradually as the structure reaches outward into space.
Based on the scale of the solar disk, this prominence extends approximately 20,000 to 25,000 miles above the Sun’s surface, roughly equivalent to stacking about three Earths on top of one another. Even at this scale, it represents an immense and highly dynamic solar feature.
Just inside the disk, a dark filament is visible running roughly parallel to the limb near the same region, likely part of the same magnetic system viewed against the solar surface. This pairing of filament and limb prominence provides a compelling view of the Sun’s three-dimensional magnetic structure.
The surrounding chromosphere displays a finely textured, mottled appearance across the disk, with subtle brightening in localized areas indicating underlying magnetic activity. The limb remains sharply defined, with faint additional prominences visible along the edge.
