Our Sun's Name, in English:

Mostly hydrogen "gas" [actually hydrogen plasma]
Solar flares and Coronal Mass Ejections (CMEs):
Explosions on the Sun's surface.
The Solar Cycle (and its length):
An 11 year cycle during which the Sun's North and South magnetic poles flip.
Three things that increase and decrease during each Solar Cycle:
Numbers of Sunspots, Solar Flares + CMEs, and overall brightness
Dark, cooler areas on the Sun's surface.
Locations where sunspots form:
Areas on the sun where the Sun's magnetic field is especially strong.
Effects of solar flares and coronal mass ejections:
1) Auroras (northern lights). 2) Interference with radio transmissions and 3) Power outages.
