Solar activity is currently at very low levels. However, a group of new sunspots are emerging over the southeastern limb and the chance of flares is increasing with it. This new group is increasing the solar EUV flux absorbed in the Earth’s
By combining different images of the Sun, taken almost at the same time on June 7, 2013, the underlying magnetic structure of the Sun and how it appears above the solar surface can be revealed. SDO engineers combined a magnetic image of the Sun, where darker and
On May 9-10, the Moon will pass directly in front of the sun over the South Pacific, producing the first (annular) solar eclipse this year. At greatest eclipse, 95-98% of the sun’s surface will be covered. An annular eclipse occurs when the Moon eclipses the
On May 1, 2013, Active Region just around the left edge of the Sun erupted with a huge coronal mass ejection (CME). The video bellow shows combined imagery from NASA’s SDO, SOHO and STEREO heliophysics fleet.
Solar Dynamics Observatory (SDO) provided a
ESA’s Space Science website released an unique portrait of a solar storm heading straight for Earth, based on data collected by the ESA/NASA SOHO space observatory during a coronal mass ejection. Imagery shows a huge cloud of magnetised plasma ejected
An annular solar eclipse will take place on May 9/10, 2013, with a magnitude of 0.9544. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring the image of the Sun for a
A spectacular prominence eruption was observed on the Sun on May 1, 2013 at 02:30 UTC. The event was classified as a farside eruption from active region located beyond eastern limb. This was the largest such event in quite some time now.
Powerful blast was unleashed
In the three years since it first provided images of the sun in the spring of 2010, NASA’s Solar Dynamics Observatory (SDO) has had virtually unbroken coverage of the sun’s rise toward solar maximum, the peak of solar activity in its regular 11-year cycle. This video
On March 2, 2013, NASA’s Solar Dynamics Observatory (SDO) entered its semiannual eclipse season, a period of three weeks when Earth blocks its view of the Sun for a period of time each day. On March 11, 2013 SDO experienced two different eclipses – The Earth and the
Researchers have found signs of an energy source in the solar wind, a hot and fast flow of magnetized gas that streams away from the sun’s upper atmosphere. Solar wind is made of hydrogen and helium ions with a sprinkling of heavier elements. Solar wind is
