Solar flares are ranked by strength, with X-class flares being the most powerful. Following the flare came a coronal mass ejection , which is when the sun shoots out blobs of solar plasma and magnetic field that—if they reach Earth—can interact with our planet’s atmosphere, triggering. It’s unclear whether today’s outburst will hit Earth—CMEs travel at varying speeds, with some taking days to cross the distance between the sun and our planet..

According to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, it is possible that northern parts of the contiguous U.S. could see auroras on Friday evening. Although AR4274 will be unable to impact Earth on the sun’s far side, the star’s approximately 27-day spin may carry the active region back within firing range. The exact times of solar maximum—and its opposite, solar minimum—are generally determined months after the fact and are based exclusively on the number of sunspots visible on our star. Powerful solar outbursts, however, often continue throughout the initial years of the declining phase of the activity cycle.has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.always educates and delights me, and inspires a sense of awe for our vast, beautiful universe.
