Balloon Observations of Galactic Cosmic Ray Helium before and during a Forbush Decrease
The energy spectrum of galactic cosmic ray Helium was measured in two different balloon experiments launched four days apart from Canada: SMILI-I on 1-Sept-1989 and MASS on 5-Sept-1989. A slow Forbush decrease began on 4-Sept-1989 and had not reached its maximum at the time of the MASS flight. Comparison of the balloon measurements shows a fractional crease of 0.37 to 0.15 in the Helium flux be...
متن کاملShort-period variability in the galactic cosmic ray intensity: High statistical resolution observations and interpretation around the time of a Forbush decrease in August 2006
[1] On 20 August 2006 a Forbush decrease observed at Polar in the Earth’s magnetosphere was also seen at the INTEGRAL spacecraft outside the magnetosphere during a very active time in the solar wind. High-resolution energetic particle data from ACE SIS, the Polar high-sensitivity telescope, and INTEGRAL’s Ge detector saturation rate, which measures the galactic cosmic ray (GCR) background with ...
متن کاملPrecipitation, cloud cover and Forbush decreases in galactic cosmic rays
The results of a study to explore variations in cloud cover, over regions that are minimally affected by rainfall and heavy rainfall, and that are coincident with variations in the galactic cosmic ray flux, are presented. Using an extensive record of global satellite derived cloud and rainfall products from the International Satellite Cloud Climatology Project (ISCCP) D1 data series and Xie and...
متن کاملApproaching the knee – balloon-borne observations of cosmic ray composition
Below the knee in the cosmic ray spectrum, balloon and spacecraft experiments offer the capability of direct composition and energy measurements on the primary particles. A major difficulty is obtaining enough exposure to extend the range of direct measurements sufficiently high in energy to permit overlap with ground-based observations. Presently, balloon and space measurements extend only up ...
متن کاملObservations of galactic cosmic rays and the anomalous helium during Ulysses passage from the south to the north solar pole
We compare observations of the modulated intensities and spectra of galactic cosmic ray nuclei and anomalous heliumabove 30MeV/nmeasured by theCOsmic andSolar Particle INvestigations (COSPIN) High Energy Telescope (HET) on Ulysses with similar observations from the IMP-8 earthorbiting satellite between September 1994 and August 1995. During this interval Ulysses made a rapid scan of solar latit...
