M1.3 solar flare ejected, CME arrives on June17th

On June 14th around 08:10 UTC, a magnetic filament near the sun's eastern limb became unstable and erupted. The resulting blast hurled a bright and massive CME into space: The expanding cloud was observed by 3 spacecraft: STEREO-A, STEREO-B and SOHO....

M2.5 solar flare, CME expected on June 9 and 10

On June 7th at 0641 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The resulting blast produced an M2-class solar flare, an S1-class radiation storm, and an unbelievable movie:Much of the plasma thrown up by the blast simply fell

Sundiving comet and coronal mass ejection

A comet dove into the sun on May 11th and seemed to trigger a massive eruption. Watch the movie, then scroll down for further discussion. A comet goes in; a CME comes out. Coincidence? Probably, yes, the sequence was coincidental. The comet disintegrated

Spectacular CME, active region approaching Earth

A sunspot located just behind the sun's eastern limb erupted during the waning hours of May 9th, hurling a spectacular coronal mass ejection into space: movie. NASA's Solar Dynamics Observatory photographed hot magnetic loops towering over the edge of the sun in the

February solar flare was sparked by five spinning sunspots

The giant solar flare unleashed in February was caused by five rotating sunspots working in concert, the UK's National Astronomy Meeting has heard.Images released from the Solar Dynamics Observatory (SDO) clearly show the sunspots, which are centres of magnetic

Heating up of solar storms season

Sun woke up after three years of sleep. Several powerful solar flares occurred in recent months, with a February 14 blast as the strongest and  the most powerful outburst in more than four years. Considering surface of Sun dotted with sunspots and recent activity,

Visible sunspots and equinox conjunction

Sunspots 1164 and 1166 are so large, people are noticing them at sunrise and sunset when the sun is dimmed by clouds and haze. The dark cores of these regions are many times wider than Earth, so they are conspicuous even from a distance of 93 million miles.

The scientists are puzzled with phenomenon of "Two Suns"

Over 80% of all solar systems have multiple suns, so is it possible that we live in a binary solar system with two suns as well? Recent discoveries point to the existence of an old brown dwarf. Our solar system is surrounded by a vast collection of icy bodies called...
