Report  Web Desk : NEW YORK: National Aeronautics and Space Administration (NASA) has released a timelapse of a sunspot recorded for around two weeks which shows the stunning intensity of our star. The sunspot came on surface on July 5, 2017. NASA’s Solar Dynamics Observatory watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun. The satellite continued to track the region as it grew and eventually rotated across the Sun and out of view on July 17. With their complex magnetic fields, sunspots are often the source of interesting solar activity: During its 13-day trip across the face of the Sun, the active region — dubbed AR12665 — put on a show for NASA’s Sun-watching satellites, producing several solar flares, a coronal mass ejection and a solar energetic particle event. Such sunspots are a common occurrence on the Sun, but less frequent at the moment, as the Sun is moving steadily toward a period of lower solar activity called solar minimum — a regular occurrence during its approximately 11-year cycle. Scientists track such spots because they can help provide information about the Sun’s inner workings. 02
