Space Weather and Earth's Aurora
Aurora are colorful lights in the night time sky primarily appearing in Earth's polar regions. But what causes them? The culprit behind aurora is our own Sun and the solar plasma that is ejected during a magnetic event like a flare or a coronal mass ejection. This plasma travels outward along with the solar wind and when it encounters Earth's ...

It’s #SunDay! This week’s (Dec. 5 - 11) space weather report includes: · 1 X-class flare · 18 M-class flares · 42 coronal mass ejections · 1 geomagnetic storm This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. The X-class flare, which erupted just after midnight Eastern time on Dec. 8, appears at about 1:26 in the video, on the right just below the Sun’s equator. Solar eruptions occur when the Sun's magnetic fields become twisted and tangled. Most flares tend to e
