Sun Blasts an X-Class Flare at the Earth You know the drill, the Sun has blasted a major flare at us (two in fact).
That means it's time to head out, watch the skies, and hope to see a beautiful aurora display.

Peering into the solar interior.
The sun emitting the solar flare, seen in 304 angstrom light.
The flare was directed toward Earth, Space.com reported, and that meant it caused a bit of trouble for earthlings.
According to NOAA's Space Weather Prediction Center, radiation released by the flare caused a radio blackout.
Solar flares occur when magnetic energy that has built up in the solar atmosphere is suddenly released.
The sun emitted a significant solar flare, peaking at 7:28 p.m. EST on Dec. 19, 2014.
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. This flare is classified as an X1.8-class flare.
X-class denotes the most intense flares, while the number provides more information about its strength.
An X2 is twice as intense as an X1, an X3 is three times as intense, etc.
Published on May 1, 2015 Over a six-hour period on April 21, 2015, NASA's Solar Dyanmics Observatory (SDO) observed a wing-like prominence eruption. SDO views the sun in various wavelengths of the extreme ultravoilet, including 171 (shown in gold) and 304 (shown in orange) angstroms. : "This video is public domain and can be downloaded Like our videos?

A giant, swirling plume of superheated plasma churned above the surface of the sun for 40 hours last week
while a NASA spacecraft looked on.
NASA's sun-studying Solar Dynamics Observatory (SDO) captured dramatic time-lapse video of the solar tornado,
which raged from Sept. 1 through Sept. 3.(2015)

Solar wind – that is, the stream of charged electrons and protons that are released from the upper atmosphere of the Sun –
is a constant in our Solar System and generally not a concern for us Earthlings. However, on occasion a solar wind shock wave or
Coronal Mass Ejection can occur, disrupting satellites, electronics systems, and even sending harmful radiation to the surface.

There’s an old Robert Heinlein saying that goes “climate is what you expect, weather is what you get,”
And the weather certainly kept folks guessing right up until the start of today’s eclipse. And though much of the
UK and tracks along the Faroe Islands were clouded out, folks who made the trek up to Svalbard were treated to a fine view of totality,
while observers across Europe caught stages of the eclipse through its partial phases.
Many more managed to capture glimpses of the eclipse thanks to our good friends over at Slooh and the Virtual Telescope project.
What’s better than a full 180-degree digital theater experience that takes you into the heart of our Sun
to see how solar storms form? Why, all of that accompanied by a rumbling narration by Benedict Cumberbatch, of course.
Flaring, active regions of our sun are highlighted in this new image combining observations from several telescopes.
High-energy X-rays from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) are shown in blue; low-energy X-rays from Japan's Hinode
spacecraft are green; and extreme ultraviolet light from NASA's Solar Dynamics Observatory (SDO) is yellow and red. All three telescopes captured their solar images around the same time on April 29, 2015. The NuSTAR image is a mosaic
made from combining smaller images. The active regions across the sun’s surface contain material heated to several millions of degrees.
The blue-white areas showing the NuSTAR data pinpoint the most energetic spots. During the observations, microflares went off,
which are smaller versions of the larger flares that also erupt from the sun's surface. The microflares rapidly release energy and heat
the material in the active regions.
NuSTAR typically stares deeper into the cosmos to observe X-rays from supernovas, black holes and other extreme objects.
But it can also look safely at the sun and capture images of its high-energy X-rays with more sensitivity than before.
Scientists plan to continue to study the sun with NuSTAR to learn more about microflares, as well as hypothesized nanoflares,
which are even smaller.
In this image, the NuSTAR data shows X-rays with energies between 2 and 6 kiloelectron volts; the Hinode data, which is from the X-ray Telescope
instrument, has energies of 0.2 to 2.4 kiloelectron volts; and the Solar Dynamics Observatory data, taken using the Atmospheric
Imaging Assembly instrument, shows extreme ultraviolet light with wavelengths of 171 and 193 Angstroms.
Note the green Hinode image frame edge does not extend as far as the SDO ultraviolet image, resulting in the green portion
of the image being truncated on the right and left sides.

Published on Dec 1, 2015 Dr. Joe Gurman of NASA's Goddard Space Flight Center provides commentary on selected shots from SOHO's 20 years in space.
After 20 years in space, ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, is still going strong. Originally launched in 1995
to study the sun and its influence out to the very edges of the solar system, SOHO revolutionized this field of science, known as heliophysics,
providing the basis for nearly 5,000 scientific papers. SOHO also found an unexpected role as the greatest comet hunter of all
time—reaching 3,000 comet discoveries in September 2015.
When SOHO was launched on Dec. 2, 1995, the field of heliophysics looked very different than it does today.
Questions about the interior of the sun, the origin of the constant outflow of material from the sun known as the solar wind,
and the mysterious heating of the solar atmosphere were still unanswered. Twenty years later, not only do we have a much better
idea about what powers the sun, but our entire understanding of how the sun behaves has changed.

Uploaded on Dec 2, 2011 Happy 16th SOHO! Launched December 2, 1995, SOHO has been giving us a 24/7 eye on the Sun for about 1 1/2 solar activity cycles.
It has allowed us to see the Sun as it has never been seen before. Though some of the instruments have now been replaced by SDO many
of its 12 instruments are still in operation, especially the LASCO C2 and C3 coronagraphs which are still vital in our daily monitoring of the Sun. Credit: NASA / ESA SOHO Category Science & Technology License Standard YouTube License
Published on May 14, 2013 This is a collection of images taken by the instruments on-board the Solar and Heliospheric Observatory' (SOHO)
of solar flare associated with the Halloween Storm of 2003. It starts with is a zoomed in view of the flare then shifts
to a full solar disk view. This is followed by the LASCO C2 coronograph view and then the LASCO C3 coronograph view.
The coronographic view end when the CCD sensors are overwhelm by the ejected solar particles.
This is the largest solar flare of the space age to date.

Published on Feb 12, 2016 The sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on Feb. 11, 2010,
SDO keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material
coursing through the sun's atmosphere, the corona. SDO's sixth year in orbit was no exception.
This video shows that entire sixth year -- from Jan. 1, 2015, to Jan. 28, 2016, as one time-lapse sequence.
At full quality on YouTube, this video is ultra-high definition 3840x2160 and 29.97 frames per second. Each frame represents 2 hours.
A downloadable version has a frame rate of 59.94 with each frame representing 1 hour. See below for the link.
SDO's Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths.
The images shown here are based on a wavelength of 171 angstroms, which is in the extreme ultraviolet range and
shows solar material at around 600,000 kelvins (about 1,079,540 degrees F). In this wavelength it is easy to see the sun's 25-day rotation.
During the course of the video, the sun subtly increases and decreases in apparent size. This is because the distance between the
SDO spacecraft and the sun varies over time. The image is, however, remarkably consistent and stable despite the fact that SDO
orbits Earth at 6,876 mph, and Earth orbits the sun at 67,062 mph.
Scientists study these images to better understand the complex electromagnetic system causing the constant movement on the sun,
which can ultimately have an effect closer to Earth, too: Flares and another type of solar explosion called coronal mass ejections
can sometimes disrupt technology in space. Moreover, studying our closest star is one way of learning about other stars in the galaxy.

During a December 2013 solar flare, three NASA missions observed a current sheet form – a strong clue for explaining what initiates the flares.
This animation shows four views of the flare from NASA’s Solar Dynamics Observatory, NASA’s Solar and Terrestrial Relations Observatory,
and JAXA/NASA’s Hinode, allowing scientists to make unprecedented measurements of its characteristics.
The current sheet is a long, thin structure, especially visible in the views on the left.
Those two animations depict light emitted by material with higher temperatures, so they better show the extremely hot current sheet.

NASA's Solar Dynamics Observatory captured this imagery of a solar flare – as seen in the bright flash –
around 8:30 p.m. EDT on April 17, 2016. A loop of solar material can also be seen rising up off the right limb of the sun.
