Sun Major Solar Flares

A most powerful solar flare erupted from the sun on March 4 sending an explosion of plasma and charged particles hurtling toward Earth. Flares occur when accelerated charged particles, mainly electrons, interact with the plasma medium. Solar flares, depending on the power of X-ray, are classified as A, B, C, M or X. According to the Space Weather Prediction Center operated by the National Weather Service the latest flare was an X1.1-class solar flare and exploded from the surface of the sun at 11:13 p.m. EST (0413 GMT March 5).

Sun Unleashed 5 Solar Eruptions in 2 Days

Sun unleashed five solar eruptions in only two days last week. The solar storms flared up between February 23 and 24 and exploded from nearly all areas of the star, including the top, bottom, left and right sides of the solar disk as seen by space-based observatories, according to NASA scientists. In fact, four of these outbursts came within a single 24-hour period. One of the eruptions churned out an impressive magnetic filament in the early hours of February 24. This triggered the first of two coronal mass ejections (CMEs) that were blasted toward Earth.

Strongest Solar Radiation Storm in 7 Years

A powerful solar eruption is expected to blast a stream of charged particles toward Earth on January 24, as the strongest radiation storm since 2005 rages on the sun. The solar flare spewed from sunspot 1402, a region of the sun that has become increasingly active lately. Several NASA satellites, including the Solar Dynamics Observatory, the Solar Heliospheric Observatory (SOHO), and the Stereo spacecraft observed the massive sun storm. According to NOAA, this is the strongest solar radiation storm since May 2005. A preliminary inspection of SOHO/STEREO imagery suggests that the CME will deliver a strong glancing blow to Earth’s magnetic field on January 24-25 as it sails mostly north of our planet.
