modern astronomers study the Sun?
LearningTargets:Ican…….
SCI.ASTR.11.4.1 Explain what some of the reasons are why
astronomers study the Sun.
SCI.ASTR.11.4.2 Define the solar constant, and explain why it is
important to know if it is truly constant with time.
What are the major layers of the Sun?
Why is the sunspot cycle carefully
monitored from Earth?
What are some ways that a solar flare
and/or unusually big blast of solar wind
can affect Earth’s environment?
What is the solar constant? Why is it
important to know if it is truly constant or
if it varies with time?
