On November 13th 2019, Active Region 12752 first came around the western limb of the Sun. The above images and video show AR12752 over the course of approximately 2 weeks as it moves across the solar disk. Comprised of over 2500 images taken by XRT, the video shows the entirety of AR12752's life span from first visualization to eventual decay.
Monitoring active regions such as this one across the full span of their life cycle is critical to our understanding of the Sun. While dynaminic events in ARs (such as flares or eruptions) are revealing and exciting, studying the full life cycle of the AR, including decay, can provide important insight into the solar energy transfer process.
Although AR12752 is no longer with us, the data obtained from its fleeting life can continue to illuminate the science behind how the sun works. Rest in Peace AR12752 (11/13/2019 to 11/25/2019). You will be missed.
