AR 12938 - Slow Building Active Region on Left Limb
The slow build-up of a solar active region, as seen in AIA 171 Angstrom filter. Correction is applied for the instrument Point-Spread Function (PSF).
Solar Dynamics Observatory (SDO) operates in a geosynchronous orbit around Earth to obtain a continuous view of the Sun. The particular instrument in this visualization records imagery in the ultraviolet portion of the spectrum at wavelengths normally absorbed by Earth's atmosphere - so we need to observe them from space.
This image sequence follows the slow build of loops over an active region (left edge of the solar limb). The moon briefly passes between the Sun and SDO (starting around 07:07TAI to 07:51TAI).
