Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.
SOLAR ACTIVITY IS INTENSIFYING: In the last 24 hours alone, the sun has produced more than 19 solar flares. The tally includes five M-class explosions and a powerful X2.2-class flare, described below. The fusillade is likely to continue as colossal sunspot complex AR2993-94 turns toward Earth in the days ahead
