      The report treats the cosmic ray variations connected with the changes of atmospheric tem-perature and solar activity level and the va-riations which are probably due to zonal cosmic ray modulation. A new type of cosmic ray variations, so called zonal cosmic ray modulation, was found in the lower atmosphere from the sonde measurement results /1/.

Abstract. The relationship between magnetic clouds, cosmic ray decreases and geomagnetic storms has been investigated by using some cosmic ray hourly intensities recorded with ground-based monitors at Alert, Deep River and Mount Washington, as well as the geomagnetic activity Dst index, and the interplanetary magnetic field (IMF) and the solar wind plasma (SWP) bulk-speed, density and Cited by: 1.

A series of cosmic-ray balloon flights was carried out in near Rome. The instrumentation used is described and the results are reported. It is shown that all the intensity versus height profiles obtained correspond to quiet solar and geomagnetic conditions, so that some reference height profiles of the “ normal ” cosmic-ray intensity at our latitudes are now available.

considers cosmic ray flux during that period. Since the sun was more active ~ 4 Gyr ago, cosmic ray shielding would have been higher from intense solar winds.

The geomagnetic model It has been already noticed that if a primary cosmic ray (energy E, charge Z) traversing the geomagnetic field is observed by a detector placed in YangBaJing, its trajectory shows a deviation along the East–West direction [5]2 which in first approximation can be written as DWC Z.

In a recent publication, Daniel García-Fernández and colleagues have used measurements from a balloon-borne antenna array to produce a cosmic ray flux the first time the spectra were produced using the radio technique exclusively, avoiding the need to carry e.g.

plastic stacks to record cosmic ray tracks. A cosmic ray travels 60 km through the earth's atmosphere in μs, as measured by experimenters on the ground. How long does the journey take according to the cosmic ray.

Computers are used to track cosmic ray paths through Earth's magnetic field, and to determine how the starting direction ("asymptotic direction") is related to the impact point.

When the primary cosmic ray strikes an atom in Earth's atmosphere, the collision may produce one or more new energetic particles called "secondary" cosmic rays. This book presents the most updated review of our current knowledge of cosmic gamma-ray sources.

Besides chapters devoted to each type of known gamma-ray emitting object, it provides a self-contained introduction to gamma-ray astrophysics, including a description of the relevant physical processes, a guide through the basic phenomenology, and the prospects for further advances.5/5(1).
