Sunspots and Space Weather
Name: _________________________________ Date: _____________
Can events that happen over 90 million miles away really have an effect on Earth? Although sunspots look like tiny dots on the solar surface, they can have a huge effect on "space weather." You'll find out more in this Planet Diary activity.
- Start at NASA's Sunspots page. What are sunspots?
- Why do sunspots appear dark?
- Go to the Sunspot Cycle Primer and play the video. Pause the video as you answer the questions. How long does the sunspot cycle normally last?
- What's the difference between solar minimum and solar maximum?
- How are sunspots related to the Sun's magnetic fields?
- How are sunspots related to solar flares and coronal mass ejections (CMEs)?
- What causes the Sun's magnetic fields to flip?
- What's today's space weather like? Visit the Space Weather Bureau. Look at the sidebar on the left for info about today's solar wind, solar flares, and sunspots. Imagine you're a space weather reporter. What's your report for today?
