Book Synopsis A Comparison of Reported Solar Flare Occurrence Times and Flare Patrol Times, 1955-1964 by : Ronald T. Podsiadlo
Download or read book A Comparison of Reported Solar Flare Occurrence Times and Flare Patrol Times, 1955-1964 written by Ronald T. Podsiadlo and published by . This book was released on 1967 with total page 20 pages. 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 and published by . This book was released on 1967 with total page 458 pages. 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.
Book Synopsis A Compilation of Solar Radio Sweep-frequency Observations, 1955-1964 by : Hans J. E. Fischer
Download or read book A Compilation of Solar Radio Sweep-frequency Observations, 1955-1964 written by Hans J. E. Fischer and published by . This book was released on 1968 with total page 44 pages. 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 and published by . This book was released on 1966 with total page 32 pages. 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.

Book Synopsis Flare Occurrence Tomorrow as a Function of Area and Flariness of Sunspot Today by : Alfred E. Reilly
Download or read book Flare Occurrence Tomorrow as a Function of Area and Flariness of Sunspot Today written by Alfred E. Reilly and published by . This book was released on 1969 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: An objective technique has been developed for estimating the probability of occurrence of solar flares in a particular sunspot group using both the size of the sunspot group and its 'flariness'. Tables are given which indicate the probability that at least one flare of importance two or greater will occur tomorrow, given the area and flariness of the sunspot group today. (Author).
Book Synopsis Constructing Solar Flare Events by Computer by : Hans J. E. Fischer
Download or read book Constructing Solar Flare Events by Computer written by Hans J. E. Fischer and published by . This book was released on 1969 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program has been developed which processes and groups individual observations of solar flares which describe the same feature. From each group of observations a consolidated description of the flare 'event' is produced. The report details the methods by which these groups are formed and the subsequent consolidated descriptions achieved. (Author).

Book Synopsis The Operating History of the International Solar Flare Patrol, 1955-1964 by : Delos C. Jensen
Download or read book The Operating History of the International Solar Flare Patrol, 1955-1964 written by Delos C. Jensen and published by . This book was released on 1967 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A decade of data on the operation of the international solar flare patrol has been collected and analyzed. These data were compiled from World Data Centers A and C, and from the individual observatories. Tests were made to correct errors introduced in the recording and handling of the data. This paper describes the data sources, error editing program employed, and the magnetic tape which has been prepared and contains the available hours of H-alpha patrol from 55 observatories for the period 1955-1964. A few tables are included showing some of the information available from the tape.

Book Synopsis Collected and Corrected Solar Flare Reports, 1955-1964 by : Hans J. E. Fischer
Download or read book Collected and Corrected Solar Flare Reports, 1955-1964 written by Hans J. E. Fischer and published by . This book was released on 1966 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flare data were compiled primarily from the flare lists of the IAU Quarterly Bulletin and a magnetic tape obtained from the Institute for Telecommunication Sciences and Aeronomy (ITSA). This tape was assembled from the CRPL-F Part B series (1955 through 1964) and included sub-flare reports. Altogether, 84,600 reports were compiled. In preparing the revised tape, tests were made for errors that were introduced at various stages in the handling of the data. Some errors were detected by comparing the entries for flare time, position, and importance of the flare reports found in both the CRPL and IAU flare lists. Only slightly more than one-third of all reports were so compared, but these included practically all flares of importance> or = 1 during the period 1955 through 1962. Errors in reported flare areas were detected by matching reports between the two flare lists and by testing the areas as a function of central distance. This check uncovered flare reports in which the measured and corrected areas were reversed. Other errors were detected by checking for consistency of the information within each flare report. These various tests disclosed a 12.5 percent error in the flare reports of the CRPL-F Part B series, and an 11.2 percent error in the Quarterly Bulletin flare list. After correction of all identified errors, the revised magnetic tape listing may still contain a 5 percent error. Most of these discrepancies are in the sub-flare reports.
