Solar Wind Exercise



Exercise 1



To what solar feature can this solar wind measurement be linked: Coronal Mass Ejection or a Coronal Hole?
Link a time and place in the low solar corona of this feature using the movies and the link below. To solve this, calculate at what time the solar plasma at L1 left the solar surface.
Is the interplanetary magnetic field associated to this solar feature pointing towards or away from the Sun?

Exercise 2



To what solar feature can the solar wind measurement on Dec 10 be linked: Coronal Mass Ejection or a Coronal Hole?
Link a time and place in the low solar corona of this feature using the movies and the link below. To solve this, calculate at what time the solar plasma at L1 left the solar surface.
Is there a satellite that could help us to make a better estimate of the arrival time of the solar plasma that left the Sun?
