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. Scientists closely monitor these events because the most powerful geomagnetic storms can disrupt satellites in orbit, cause communications interference, and damage other electronic infrastructure. But, one of the less harmful effects of geomagnetic storms is that they can amp up normal displays of Earth’s auroras. The February 24 eruption was captured in a video by NASA’s Solar Dynamics Observatory. The filament, which is visible in the extreme ultraviolet wavelength, shoots out from the sun, sending clouds of plasma into space. Accroding to scientists filaments are strands of darker, cooler solar material that hover above the surface of the sun by magnetic forces. The CME from the February 24 solar eruption was weak, however, and did not set off a strong geomagnetic storm. After traveling through space, the CME hit Earth’s magnetic field on February 26 at 4 p.m. EST (2100 GMT).
