SDO 2014 spring eclipse season has begun

Twice every year, around the time of the equinoxes, Earth can pass directly between the Sun and NASA's Solar Dynamics Observatory (SDO), producing a series of beautiful eclipses. For the next 3 weeks the Earth will pass between SDO and the Sun around 07:30 UTC

Solar Dynamics Observatoy (SDO) – Year 4

NASA's Solar Dynamics Observatory (SDO), launched on February 11, 2010, 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. The

Our changing climate and the variable Sun

Our changing climate and the variable Sun

Solar physicists around the world today are wondering: has the Sun fallen silent? In 2013, the Sun began the peak phase of its 11-year sun spot cycle called the Solar Maximum when sunspot production should be at its highest. However, the lack of sunspot activity has

Argos (or Argus Panoptes) was the 100-eyed giant in Greek mythology.

While NASA Solar Dynamics Observatory (SDO) has significantly less than 100 eyes, seeing connections in the solar atmosphere through the many filters of SDO presents a number of interesting

The weak solar cycle and its consequences

At this year's Fall Meeting of American Geophysical Union, held in San Francisco (December 9 – 13), several scientists made a presentation on weak Solar Cycle 24 and its consequences.

They agree that the current solar cycle is on track to be

This movie shows 23 of the 26 M- and X-class flares on the Sun between 18:00 UTC on October 23 and 15:00 UTC on October 28, 2013, as captured by NASA's Solar Dynamics Observatory. It also shows the coronal mass ejections, great clouds of solar

Sungrazer's final approach to the Sun

Sungrazer's final approach to the Sun

SOHO's LASCO C3 coronagraph treated us with another movie of comet's death plunge into the Sun. Like other comets that were recorded during August, today's sungrazer belongs to Kreutz Sungrazer family. Those
