Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA's Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 900 miles per second, which is a fairly fast speed for CMEs. Historically, CMEs at this speed have caused mild to moderate effects at Earth.Update: On March 17, 2013, at 1:28 a.m. EDT, the coronal mass ejection (CME) from March 15 passed by NASA's Advanced Composition Explorer (ACE) as it approached Earth. Upon interacting with the giant magnetic bubble surrounding Earth, the magnetosphere, the CME caused a kind of solar storm known as a geomagnetic storm. The storm initially caused a mild storm rated on NOAA's geomagnetic storm scales as a G2 on a scale from G1 to G5, and subsequently subsided to a G1. In the past, storms of this strength have caused auroras near the poles but have not disrupted electrical systems on Earth or interfered with GPS or satellite-based communications systems. || ", "release_date": "2013-03-18T08:00:00-04:00", "update_date": "2023-05-03T13:52:18.582207-04:00", "main_image": { "id": 467240, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011200/a011225/LASCO_C2_March_15_CME_Triptych_No_Labels_web.jpg", "filename": "LASCO_C2_March_15_CME_Triptych_No_Labels_web.jpg", "media_type": "Image", "alt_text": "The ESA and NASA Solar Heliospheric Observatory (SOHO) captured these images of the sun spitting out a coronal mass ejection (CME) on March 15, 2013, from 3:24 to 4:00 a.m. EDT.
