A correlative study of SSC's, interplanetary shocks, and solar activity [PDF]

open access: yes
A total of 93 SSC's were examined during the four year period from 1968 to 1971 at and near the peak of the solar activity cycle. Of the 93 SSC's 81 could be associated with solar activity, such as solar flares and radio bursts of Type II and Type IV ...

Solar wind disturbances in th outer heliosphere caused by successive solar flares from the same active region [PDF]

open access: yes, 1983
Solar wind disturbances caused by successive flares from the same active region are traced to about 20 AU, using the modeling method developed by Hakamada and Akasofu (1982).

Two classes of solar energetic particle events associated with impulsive and long duration soft X-ray flares [PDF]

open access: yes
Solar energetic particle events observed in space have different properties depending on the class of associated flare. Impulsive flares, which occur low in the corona in regions of high energy density, are associated with particle events which are ...

Large-scale interplanetary magnetic fields: Voyager 1 and 2 observations between 1 AU and 9.5 AU [PDF]

open access: yes
The large-scale radial and temporal variations of the interplanetary magnetic field strength B observed by Voyagers 1 and 2 are discussed. Two components of the magnetic field strength were considered: (1) an average component, B sub zero, based on solar

Criteria of interplanetary parameters causing intense magnetic storms (Dst less than -100nT) [PDF]

open access: yes
Ten intense storms occurred during the 500 days of August 16, 1978 to December 28, 1979. From the analysis of ISEE-3 field and plasma data, it is found that the interplanetary cause of these storms are long-duration, large and negative IMF B sub Z events,

Nonthermal Acceleration of Electrons, Positrons, and Protons at a Nonrelativistic Quasi-parallel Collisionless Shock

open access: yesThe Astrophysical Journal
Energetic positrons have been observed in the interstellar medium, and high-energy positrons with relativistic energies up to approximately 1 TeV have been detected in Galactic cosmic rays.

Predicting the arrival times of solar particles [PDF]

open access: yes
A procedure has been developed to generate a computerized time-intensity profile of the solar proton intensity expected at the earth after the occurrence of a significant solar flare on the sun.

Evolution of Electron Acceleration by Corotating Interaction Region Shocks at 1 au

open access: yesThe Astrophysical Journal Letters
We present the first observations of in situ electron acceleration at corotating interaction region (CIR) shocks near 1 au, utilizing measurements from Wind and Magnetospheric Multiscale (MMS) mission in the interplanetary medium. As the forward (reverse)
