Sun Unleashes 5 Solar Eruptions in 2 Days
Space.com – “Things on the sun have certainly been heating up. Our closest star unleashed five solar eruptions in only two days last week, producing extraordinary northern lights displays for lucky skywatchers over the weekend.
The solar storms flared up between Feb. 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 Feb. 24. This triggered the first of two coronal mass ejections (CMEs) that were blasted toward Earth. CMEs are massive eruptions of solar plasma and charged particles that can produce potentially harmful geomagnetic storms when the they hit Earth’s magnetic field lines.
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 (also known as the northern and southern lights).
The Feb. 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.” Read more.
