The word 'coronal' is correct and usable in written English.
It can be used as an adjective or noun. Example sentence: The scientist studied the coronal lines of the star.
Ohhh... OK, for example: coronal mass ejections - they're leaping bursts of solar plasma that can cause devastating electromagnetic interference on Earth.
If the sun were to have one of its regular temper tantrums, known as coronal mass ejections, which produce huge bursts of ionising radiation, that limit might be far exceeded.When the stars are rightBoth missions hope to use SpaceX's Falcon Heavy, a planned upgrade of its existing Falcon rocket.
That field, weak as it is compared with the one that keeps the shopping list attached to your refrigerator door, last week saved your life, as it does each time the sun spews out a "coronal mass ejection".
An eruption of hot plasma from the sun, called a coronal mass ejection, which could do damage to electricity grids over an entire continent, might fit the bill.
Subsequent work has shown that other solar activities, such as flares and coronal mass ejections, follow the same cycles.
And in 1989 a geomagnetic storm (a disturbance in the Earth's magnetic field caused by a coronal mass ejection) induced big electrical currents in Quebec's electricity grid, cutting power to millions of people for nine hours.
Such coronal mass ejections (CMEs), several of which occur every day, are the most violent eruptions in the solar system.
These coincided with periods when global temperatures were lower than average, though why is a matter of debate.An absence of sunspots also means an absence of solar flares and their more violent siblings, coronal mass ejections.
It has storms, in the shape of solar flares, enormous eruptions of plasma that spew charged particles out into space, and coronal mass ejections, which blast a quantity of the Sun's mass out into the solar system.
This craft has already observed immense loops of coronal gas vibrating and snapping wildly on the sun's surface.
