Characteristics of active-region sources of solar wind near solar maximum
Neugebauer, M.; Liewer, Paulett C.; Zurbuchen, Thomas
Previous studies of the source regions of solar wind sampled by ACE and Ulysses showed that some solar wind originates from open magnetic flux rooted in active regions. These solar wind sources were labeled active-region sources when the open flux was from a strong field region with no corresponding coronal hole in the NSO He 10830 Å synoptic coro…
Solar Wind Electron Parameters from ULYSSES/URAP Quasi-Thermal Noise Measurements at Solar Maximum
Issautier, K.; Moncuquet, M.; Hoang, S.
We present the solar wind plasma parameters obtained from the Ulysses spacecraft during its second pole-to-pole fast latitude scan near the 2001 solar maximum. We study the solar wind properties from the electron density and core temperature measurements made by the radio receiver on Ulysses using the method of quasi-thermal noise spectroscopy. We…
