A Comparison of Reported Solar Flare Occurrence Times and Flare Patrol Times, 1955-1964 by Ronald T. Podsiadlo Pdf

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.

Flare Occurrence Tomorrow as a Function of Area and Flariness of Sunspot Today by Alfred E. Reilly Pdf

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).

A Compilation of Solar Radio Sweep-frequency Observations, 1955-1964 by Hans J. E. Fischer Pdf

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.

Constructing Solar Flare Events by Computer by Hans J. E. Fischer Pdf

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).

The Objective Construction of a Solar-geophysical Data Base by Richard G. Hendl,Richard Godfrey Hendl Pdf

A comprehensive solar-geophysical data base has been assembled. The data base contains a wide variety of error-corrected measurements that have been spatially and temporally correlated to objectively identify those features associated with the same solar regions. The contents of the data base and the logic used to associate the different features are described. (Author).

Statistical Analysis of Shortwave Fadeout Occurrence for the Years 1955 to 1969 by Richard G. Hendl Pdf

Shortwave fadeout data for the period 1955 through 1969 were analyzed and correlated with solar flare data for the same period. Details of the analysis are presented along with various statistical presentations of the data. The validity of computerized objective procedures for matching geophysical data is shown. Some doubt is cast on the quality of the shortwave fadeout data during the early part of the period considered. (Author).

Collected and Corrected Solar Flare Reports, 1955-1964 by Hans J. E. Fischer Pdf

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.
