Study Activity

Planetarium Program: Use your planetarium program to explore the surface of the sun. In Starry Night, you should be able to use Favorites → Explorations → Sun; you may also be able to change your Viewing Location to the surface of the Sun. Use the LiveSky options to view the sun "now".

If your program allows, explore solar rotations and run time forward so that the Sun makes an entire rotation. How long does this take?

Website of the Week: Check out The Solar and Heliospheric Observatory site. Look at the pictures of the sun "now". Do you observe any activity? Sketch the position of any sunspots you observe, then return to the site every two days for ten days (total five visits). What happens to the sunspots?
