Subaru Telescope Observers Superflare Stars with Large Starspots

Tags: , , |

A team of astronomers has used the High Dispersion Spectrograph on the Subaru Telescope to conduct spectroscopic observations of Sun-like "superflare" stars first observed and cataloged by the Kepler Space Telescope. The investigations focused on the detailed properties of these stars and confirmed that Sun-like stars with large starspots can experience superflares. The team, made

NuSTAR: The most sensitive solar portrait ever taken in high-energy X-rays.

For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun. NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first picture of the sun, producing the most sensitive solar

Strong X3.1 solar flare erupted from AR2192 (@Oct. 25)

Giant sunspot erupts today with 4th substantial flare since Oct 19. Region 2192 has 'beta-gamma-delta' magnetic configuration and is capable of producing more strong to major eruptions on the Sun. Coronagraph data from the Solar and Heliospheric Observatory (SOHO) suggest that the explosion did not hurl a significant CME toward our planet. Interestingly, none of

SDO imagery suggests that a coronal mass ejection

Farsided Flares Continue

Tags: , , |

Solar flare activity continues this morning off the farside of the sun. A pair of moderate to strong solar flares took place simultaneously and the bright flashes were captured by the STEREO Ahead space craft. One of these blasts was observed around old region 1986 which is still 11 days away from returning into Earth
