Скачать или смотреть GOES-16: SUVI Observes Solar Flare

After a period of very quiet conditions, the emergence of several active regions on the sun brought solar activity back to levels that haven't been seen in more than a year. As these active regions developed, they sparked a series of solar flares and eruptions, including the one in this imagery from GOES-16's SUVI instrument, which was observed (with wavelength 195Å) on April 1 at about 21:45 UTC.

The flare itself is the rapid, intense brightening you can see in the sun’s upper right quadrant toward the beginning of the animation, but the flare was also linked to an eruption, which escaped from the sun as a coronal mass ejection. The eruption is easy to spot as the blast of material headed into space from the flaring region. Since this particular eruption was not directed toward Earth, NOAA’s Space Weather Prediction Center forecasters expected its effects be minimal.

The Solar Ultraviolet Imager or SUVI instrument aboard NOAA's GOES-16 satellite is a telescope that monitors the sun within the extreme ultraviolet (EUV) wavelength range. SUVI is used to characterize complex features on the sun and detect the occurrence of solar flares and coronal mass ejections (CMEs), thereby providing early warnings of potential Earth impacts from severe to extreme space weather.
