The event occurred in 2012, near the local maximum of sunspots that can be seen in this graph.. At 02:08 UT on 23 July 2012, a large coronal mass ejection (CME) was launched from the Sun. [3] The eruption emanated from solar active region 11520 and coincided with what was at most an X2.5-class solar flare. [4]
In the spectral class label, G2 indicates its surface temperature, of approximately 5770 K ( the UAI will accept in 2014 5772 K) and V indicates that the Sun, like most stars, is a main-sequence star, and thus generates its energy via fusing hydrogen into helium. In its core, the Sun fuses about 620 million metric tons of hydrogen each second.
CMEs typically reach Earth one to five days after leaving the Sun. The strongest deceleration or acceleration occurs close to the Sun, but it can continue even beyond Earth orbit (1 AU), which was observed using measurements at Mars [21] and by the Ulysses spacecraft. [22] ICMEs faster than about 500 km/s (310 mi/s) eventually drive a shock ...
