10-6 Effects of Magnetic Fields

Question 1

plage

Answer 1

a bright area of the sun, precursor of sunspots

Question 2

filament

Answer 2

a dark area in the corona produced by gas

Question 3

prominence

Answer 3

filaments seen edge on observed at the solar limb

Question 4

flares

Answer 4

huge prominences that escape from the sun

Question 5

coronal holes

Answer 5

dark areas which serve as escape routes for solar gases

Question 6

solar maximum flares

Answer 6

1100 flares per year, most lasting around 1 hour

Question 7

coronal mass ejection

Answer 7

eject 2 trillion tons of matter at 1.4x10^6 km/hr. Two to four days later, the highest energy gases from the ejection reach 1 AU. Most particles are deflected by the earth’s magnetic field (blue). some particles leak through and cause aurorae, disrupt radio waves, and damage satellites, etc

Question 8

extrasolar magnetic field

Answer 8

following the paths of particles emitted by a solar flare it is possible to map the solar magnetic field outside the sun. the field guides outflowing particles. particles emit radio waves that map the field
