Download or read book A Comparison of Reported Solar Flare Occurrence Times and Flare Patrol Times, 1955-1964 written by Ronald T. Podsiadlo. This book was released on 1967. Available in PDF, EPUB and Kindle. Book excerpt: A flare event list that is consistent with flare patrol times is prerequisite to a reliable, unbiased estimate of flare occurrence per unit patrol time. A comparison of the flare occurrence times and flare patrol times reported by 52 solar observatories during the period of 1955 to 1964 discloses that 12.3 percent of the flare reports (Importance = or > 1) have no reported patrol coverage. Elimination of these 'unpatrolled' flare reports reduces the number of individual flare events in the data sample by 9.7 percent. This means that flare occurrence per unit patrol time computed from the raw flare and flare patrol data is overestimated by this same percentage. In addition to eliminating 'unpatrolled' flare reports, appropriate adjustments are made in the 'patrolled' flare data so as to make each observatory's reported flare times completely consistent with its reported patrol times.

Book Synopsis A Statistical Summary of Solar Flare Reports and Observatory Practices for the Period 1955-1964 by : Delos C. Jensen

Download or read book A Statistical Summary of Solar Flare Reports and Observatory Practices for the Period 1955-1964 written by Delos C. Jensen. This book was released on 1967. Available in PDF, EPUB and Kindle. Book excerpt: This is a summary of the ten years (1955-1964) of observations of solar flares reported by 61 observatories. The flare reports have been published predominantly in the IAU Bulletin and CRPL-F Series Part B. This report summarizes the types of information contained in the flare reports, and the frequency of some parts of these reports as functions of many parameters. The results reflect the need for closer cooperation and coordination of participating observatories in recording and reporting solar flare data.

Download or read book A Compilation of Solar Radio Sweep-frequency Observations, 1955-1964 written by Hans J. E. Fischer. This book was released on 1968. Available in PDF, EPUB and Kindle. Book excerpt: The solar radio sweep-frequency observations and hours of patrol from five rad radio observatories for the period 1955 through 1964 have been compiled, edited, and put onto two magnetic tapes. One tape contains the hours of radio patrol from the observatories at Ann Arbor, Bigpine, Boulder, Sydney and Fort Davis. Another tape contains the sweep-frequency observations in the meter and dekameter wavelengths of the radio spectrum from these observatories. The sources, methods of reduction, and the format and content of the data on tape are described. Statistics related to various distributions of the radio spectral activity reported by each station are discussed and demonstrate an urgent need for standard policies in detecting, scaling, classifying, and reporting these data.

Book Synopsis Solar Flare Occurrence as a Function of Sunspot Size by : Isadore Enger

Download or read book Solar Flare Occurrence as a Function of Sunspot Size written by Isadore Enger. This book was released on 1966. Available in PDF, EPUB and Kindle. Book excerpt: An objective technique has been developed for assessing the probability of occurrence of solar flares in a particular sunspot group, given only the sizes of the sunspot group on two consecutive days. The sunspot data cover the 10-year period 1955 to 1964 and have been published in the Greenwich Photoheliographic Results. The flare data were measured at Sacramento Peak, New Mexico. The flare and spot data were combined by a simple, objective technique which depends only on the size of the spot group and the relative positions of the spot group and flare. These results show the very marked dependence of flare occurrence on the size of the spot group and a significant, but very much smaller, dependence on the change in group size from one day to the next.
