SOHO sees bright sungrazer comet

ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, saw a bright comet plunge toward the Sun on 3-4 August 2016, at nearly 1.3 million miles per hour. The comet, first spotted by SOHO on 1 August, is part of the Kreutz family of comets, a group with related orbits that broke off of a huge comet several centuries ago.


ACT system tracks solar eruptions in 3-D

Scientists at Aberystwyth University have developed an automated method for three-dimensional tracking of massive eruptions from the Sun, called Coronal Mass Ejections (CMEs). The Automated CME Triangulation (ACT) system uses data from three space-based observatories that orbit the Sun at different locations, allowing scientists to view the Sun and CMEs from different angles.
