Solar origins of solar wind properties during the cycle 23 solar minimum and rising phase of cycle 24
The solar wind was originally envisioned using a simple dipolar corona/polar coronal hole sources picture, but modern observations and models, together with the recent unusual solar cycle minimum, have demonstrated the limitations of this picture. The solar surface fields in both polar and low-to-mid-latitude active region zones routinely produce coronal magnetic fields and related solar wind s...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE Unusual solar energetic proton fluxes at 1 AU within an interplanetary CME
In mid December 2006 several flares on the Sun occurred in rapid succession, spawning several CMEs and bathing the Earth in multiple solar energetic particle (SEP) events. One such SEP occurring on December 15th was observed at the Earth just as an interplanetary CME (ICME) from a previous flare on December 13th was transiting the Earth. Although solar wind observations during this time show ty...
متن کاملGlobal distribution of the solar wind during solar cycle 23: ACE observations
[1] The composition of the solar wind can be used to determine its origin at the Sun; e.g., solar wind from coronal holes has demonstrably lower charge states than solar wind of other origins. The O/O ratio as measured by Advanced Composition Explorer (ACE) during 1998– 2008 is used to divide the solar wind into three categories: non-transient solar wind from coronal holes (hereafter referred t...
متن کاملModulation of Jovian electrons at 1 AU during solar cycles 22–23
[1] We report here, on the observation of Jovian electrons during the time period 1992 to 2002, using instruments on board SAMPEX and IMP8 at 1 AU. The Jovian electron flux diminished greatly from early 1996 to the end of 1997 and recovered subsequently and was observed till the end of 2001. The decrease in the Jovian flux was seen in three distinct instruments lasting for about two Jovian syno...
متن کاملObservations of Jovian Electrons at 1 AU
It has recently been suggested that electrons of Jovian origin are responsible for the 'quiet time increases' in the > 3-MeV electron intensity observed at I AU. Using data from the California Institute of Technology electron/isotope spectrometers on Imp 7 and 8, we have studied the temporal behavior of quiet ime electrons at I AU over the period October 1972 through May 1975. We find the lto 6...
