The Cosmic-Ray Observations of December 4, 1957
A RECENT communication from Legrand and Helary1 reports an increase in the total component of cosmic radiation at Paris on December 4, 1957. The increase amounted to about 18 per cent and extended over three hours with the maximum occurring at 2245 U.T. A small increase in the nucleonic component at Thule preceded the Paris event by about three hours. Optical and radio data indicate a flare of importance 1 on the western hemisphere of the Sun at 1657 U.T. (ref. 2).
Local Increase of Intensity of Cosmic Radiation
DURING the International Geophysical Year, no important proton event of solar origin was detected on the Earth by the different stations ; but on the other hand, high-altitude balloon flights show that arrivals of low-energy protons to the polar regions were rather frequent events. These arrivals of protons are generally preceded by a solar flare associated with a radio outburst of type IV, and are accompanied by ionospheric absorption, total or partial, in the polar regions.
RIP - General Purpose Interactive Display at HHIRF
RIP is a general purpose interactive code for display and analysis of data acquired with the Holifield Heavy Ion Research Facility (HHIRF) accelerators at Oak Ridge National Laboratory. The HHIRF data acquisition system includes a version of RIP for on-line display of one-and two-dimensional histograms on color graphic terminals and hard copy on color printer/plotters. General features of the program and interactive techniques will be described.
