Large solar prominence erupts, CME produced


A large solar prominence dubbed "the Great Wall of Plasma" erupted off the northeast limb of the Sun at approximately 13:00 UTC on March 27, 2015. This spectacular structure was more than 6x taller and 30x wider than Earth before it erupted. 

A Coronal Mass Ejection (CME) was produced, but it does not appear to be heading toward our planet. It could, however, have a small geoeffective component.

Meanwhile, a co-rotating interaction region (CIR) in advance of a negative polarity coronal hole high speed stream (CH HSS) is expected to influence ACE solar wind signatures late on March 27.

On March 28 and 29, the CH HSS wind structure is expected to become geoeffective with wind speeds approaching 700 km/s expected.

Active to minor storm conditions are expected on March 28 and 29 as effects from the CH HSS impact Earth's magnetic field.
