Seeing the Sun in a New Light: Interplanetary Magnetic Field Lines
http://www.phy6.org/stargaze/Lsun6new.htm
From DLESE Community Collection (DCC)
Comment on this resource
This lesson discusses the Sun's corona, observed from spacecraft in the extreme ultra violet (EUV) and in x-rays, including coronal holes and coronal mass ejections (CME), their effect near Earth and their monitoring from space. This section also discusses related phenomena in interplanetary space and on Earth and contains an optional class exercise in which students learn about field line preservation of flows in a highly conducting plasma, and use it to graphically obtain the shapes of interplanetary magnetic field lines. They also receive information about high-energy ions and electrons accelerated by solar activity, probably from magnetic energy, and the hazard they pose to spacefarers. Students receive an introduction to NASA's great observatories, expanding the coverage of the electromagnetic spectrum by astronomers.
