NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash on the upper left – on Feb. 22, 2024. The image shows a blend of 171 Angstrom, 193 Angstrom and 1600 Angstrom light, subsets of ultraviolet and extreme ultraviolet light.

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.Active Region 13559 now carried by solar rotation to the upper right limb of the solar disk, launches a mid-range (M6.8 class) flare. For details of this event, see the Space Weather database entry. A large arcade of plasma loops forms after the event, more visible in the 171 angstrom and 304 angstrom filters. An eclipse of the Sun by Earth provides a nice 'curtain close' for the event. For more information on the classification of solar flares, see Solar Flares: What Does It Take to Be X-Class? or X-Class: A Guide to Solar Flares. The point-spread function correction (PSF) has been applied to all this imagery. ||

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.Almost simultaneous flares at Active Region 13559 (upper left of disk) and Active Region 13561 (lower right of disk) fire off, with a combined X-ray flux equivalent of an M5.1 solar flare. For details of this event, see the Space Weather database entry for both events.For more information on the classification of solar flares, see Solar Flares: What Does It Take to Be X-Class? or X-Class: A Guide to Solar Flares.

Brighter than a shimmering ghost, faster than the flick of a black cat’s tail, the Sun cast a spell in our direction, just in time for Halloween. This imagery captured by NASA’s Solar Dynamics Observatory covers a busy few days of activity between Oct. 25-28 that ended with a significant solar flare. From late afternoon Oct. 25 through mid-morning Oct. 26, an active region on the left limb of the Sun flickered with a series of small flares and petal-like eruptions of solar material. Meanwhile, the Sun was sporting more active regions at its lower center, directly facing Earth. On Oct. 28, the biggest of these released a significant flare, which peaked at 11:35 a.m. EDT.

A movie of the Aug 21, 2017 lunar transit as viewed by the Solar Dynamics Observatory (SDO.) The Sun appears in visible light, and 171 ångstrom extreme ultraviolet light. The movie shows the Sun moving a bit because SDO has a hard time keeping the Sun centered in the image during a transit, because the Moon blocks so much light. The fine guidance systems on the SDO instruments need to see the whole Sun in order keep the images centered from exposure to exposure. Once the transit was over, the fine guidance systems started back up, once again providing steady images of the Sun.Credit: NASA/SDOWatch this video on the NASA Goddard YouTube channel. || SDO_Eclipse_Transit_Still.jpg (3840x2160) [1.4 MB] || SDO_Eclipse_Transit_Still_searchweb.png (320x180) [70.6 KB] || SDO_Eclipse_Transit_Still_thm.png (80x40) [5.5 KB] || 12688_SDO_Eclipse_Transit_H264_1080.mov (1920x1080) [126.4 MB] || 12688_SDO_Eclipse_Transit_H264_1080.webm (1920x1080) [4.6 MB] || 12688_SDO_Eclipse_Transit_ProRes_3840x2160_2997.mov (3840x2160) [2.7 GB] || 12688_SDO_Eclipse_Transit_H264_best_3840x2160_2997.mov (3840x2160) [378.1 MB] ||

The sun emitted three mid-level solar flares on July 22-23, 2016, the strongest peaking at 1:16 am EDT on July 23. The sun is currently in a period of low activity, moving toward what's called solar minimum when there are few to no solar eruptions – so these flares were the first large ones observed since April. They are categorized as mid-strength flares, substantially less intense than the most powerful solar flares. ||

The sun emitted a CME and mid-level solar flare, peaking at 2:23 p.m. EDT, on June 22, 2015. Again on June 25, 2015, a mid-level solar flare peaked at 4:16 a.m. EDT.NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event may affect Earth, please visit NOAA's Space Weather Prediction Center at http://spaceweather.gov, the U.S. government's official source for space weather forecasts, alerts, watches and warnings. This first flare is classified as an M6.6 flare and the second was M7.9. M-class flares are a tenth the size of the most intense flares, the X-class flares. The number provides more information about its strength. An M2 is twice as intense as an M1, an M3 is three times as intense, etc. ||

On August 9, 2011 at 3:48 a.m. EDT, the sun emitted an Earth-directed X6.9 flare, as measured by the NOAA GOES satellite. These gigantic bursts of radiation cannot pass through Earth's atmosphere to harm humans on the ground, however they can disrupt the atmosphere and disrupt GPS and communications signals. In this case, it appears the flare is strong enough to potentially cause some radio communication blackouts. It also produced increased solar energetic proton radiation — enough to affect humans in space if they do not protect themselves. As of March 2014, this flare is the largest of solar cycle 24. ||

One instrument watching for the comet was the Solar Dynamics Observatory (SDO), which adjusted its cameras in order to watch the trajectory. Not only does this help with comet research, but it also helps orient instruments on SDO—since the scientists know where the comet is based on other spacecraft, they can finely determine the position of SDO's mirrors. This first clip from SDO from the evening of Dec 15, 2011 shows Comet Lovejoy moving in toward the sun. Comet Lovejoy survived its encounter with the sun. The second clip shows the comet exiting from behind the right side of the sun, after an hour of travel through its closest approach to the sun. By tracking how the comet interacts with the sun's atmosphere, the corona, and how material from the tail moves along the sun's magnetic field lines, solar scientists hope to learn more about the corona. This movie was filmed by the Solar Dynamics Observatory in 171 angstrom wavelength, which is typically shown in yellow.Credit: NASA/SDO ||

On June 7, 2011 the Sun unleashed an M-2 (medium-sized) solar flare with a spectacular coronal mass ejection (CME). The large cloud of particles mushroomed up and fell back down looking as if it covered an area almost half the solar surface.SDO observed the flare's peak at 1:41 AM ET. SDO recorded these images in extreme ultraviolet light that show a very large eruption of cool gas. It is somewhat unique because at many places in the eruption there seems to be even cooler material — at temperatures less than 80,000 K.This video uses the full-resolution 4096 x 4096 pixel images at a one minute time cadence to provide the highest quality, finest detail version possible.It is interesting to compare the event in different wavelengths because they each see different temperatures of plasma. See the transcript for more notes on this.Frames for each wavelength are available on these separate pages: 304, 171, 211, and1700. ||
