Intensities of the Venusian N₂ electron-impact excited dayglow emissions

Fox, Jane L.; F. Hać, Nicholas E.

Dayglow emissions are signatures of both the energy deposition into an atmosphere and the abundances of the species from which they arise. The first N₂ dayglow emissions from Mars, the (0,5) and (0,6) bands of the N₂ Vegard-Kaplan band system, were detected by the Spectroscopy for Investigations of the Characteristics of the …

Magnetic field topology of the plasma sheet boundary layer

Nakamura, R.; Baumjohann, W.; Teh, W. -L.

magnetic field topology of the plasma sheet boundary layer (PSBL) and its neighborhood is examined using a steady, two-dimensional (2-D), ideal MHD reconstruction method. We study four PSBL crossings, from the lobe toward the plasma sheet and back into the lobe, by the Cluster spacecraft in the Earth's magnetotail around (x, y, z) = (-17.3, 4.3, -…

Ulysses observations of Jupiter's 10 h modulation in interplanetary space in 2004

Heber, B.; Kopp, A.; Dunzlaff, P.

Since the Pioneer 10/11 mission, Jupiter is known as a dominant and almost constant source of MeV electrons in the inner heliosphere. An interesting feature of the Jovian electron source is the fact that Jupiter's rotation period (~10 h) can frequently be recovered in the energy spectrum of Jovian electrons in the vicinity of the planet. However, …
