Long Duration Solar Flare & Earth-directed Coronal Mass Ejection
September 9, 2014: Earlier today, the magnetic canopy of sunspot AR2158 erupted, producing an explosion that lasted more than 6 hours. The flare peaked on Sept. 9th at 00:30 UT with a classification of M4 on the Richter Scale of Solar Flares. Long-duration flares tend to produce bright CMEs, and this one was no exception.

Coronagraphs onboard the Solar and Heliospheric Observatory observed a CME racing out of the blast site at nearly 1,000 km/s (2.2 million mph.

Most of the storm cloud is heading north of the sun-Earth line, but not all. A fraction of the CME will deliver a glancing blow to Earth's magnetic field, probably during the late hours of Sept. 11th or early hours of Sept. 12th. In the past few weeks, glancing blows from minor CMEs have sparked beautiful auroras around the Arctic Circle. This CME could do the same.

Bangkok to North Pacific (annotated) | NASA
This video was taken by the crew of Expedition 38 on board the International Space Station. The sequence of shots was taken on January 30, 2014 from 13:07:04 to 13:31:39 GMT, on a pass from northeastern Malaysia to the North Pacific Ocean, just south of the Aleutian Islands.

This video starts looking northeast toward Bangkok at night and continues to travel northeast toward Hong Kong, then continues toward the Korean Peninsula and Beijing area. Just before the video passes over the black of the Pacific Ocean, the Kamchatka Peninsula can be faintly seen, with few city lights and snow-covered. The video ends looking north/northeast toward the Aleutian Islands.

The Medusa Nebula Close-up
This close-up pan video shows the most detailed image ever taken of the Medusa Nebula (also known Abell 21 and Sharpless 2-274). It was captured using ESO’s Very Large Telescope in Chile. As the star at the heart of this nebula made its final transition into retirement, it shed its outer layers into space, forming this colorful cloud. The image foreshadows the final fate of the Sun, which will eventually also become an object of this kind.

Solar Flare from a Sharper Sun

Image Credit: Solar Dynamics Observatory/AIA, NASA
Processing: NAFE by Miloslav Druckmuller (Brno University of Technology)

http://apod.nasa.gov/apod/ap141122.html

Solar active region AR2192 was the largest recorded sunspot group of the last 24 years. Before rotating off the Earth-facing side of the Sun at the end of October, it produced a whopping six energetic X-class flares. Its most intense flare was captured on October 24 in this stunning view from the orbiting Solar Dynamics Observatory. The scene is a color combination of images made at three different wavelengths of extreme ultraviolet light; 193 angstroms shown in blue, 171 angstroms in white, and 304 angstroms in red. The emission, from highly ionized Iron and Helium atoms, traces magnetic field lines looping through the hot plasma of the Sun's outer chromosphere and corona. Beneath, the cooler solar photosphere appears dark at extreme ultraviolet wavelengths. The exceptionally sharp composite image has been processed with a new mathematical algorithm (NAFE) that adapts to noise and brightness in extreme ultraviolet image data to reliably enhance small details.
