Book excerpt: One of the largest radio bursts on record took place on May 23, 1967. Peak flux densities ranged between 23,000 flux units (10 to the minus 22nd power sq Wm/Hz) at 8800 MHz to about 370,000 units at 606 MHz. In addition to the high accuracy measurements of the peak flux densities at 606, 1415, 2695, 4995, and 8800 MHz, sweep frequency observations from 19 to 41 MHz show Type IV emission with Type II bursts occurring during the Type IV continuum. The associated flare was clearly visible in white light. In reviewing and compiling microwave radio data recorded during earlier white-light flares, it was found that all but one of eight events listed by Svestka (1966) had high microwave flux densities associated with them. In comparing radio burst intensity with optical flare importance for the series of three flares between 1809 and 2150 UT on May 23, 1967, there is only moderate agreement. The first radio burst was small; the second flare had the highest optical classification, while the third radio burst was by far the largest. The flux densities of the third radio burst may have been the highest ever recorded in the decimeter portion of the radio spectrum and among the largest four in the 8800 MHz region. It is suggested that the details of the development of the flare be followed on radio flux density plots to determine detailed correlation with particle events in space and with terrestrial effects.

Book Synopsis Solar Radio Activity in August 1972 by : John P. Castelli
Download or read book Solar Radio Activity in August 1972 written by John P. Castelli and published by . This book was released on 1973 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide variety of both conventional and infrequently observed phenomena took place during the disk passage of McMath Plage No. 11976. A summary of the more important solar radio activity is presented. The largest of the bursts on 2,4, and 7 August had proton association which is correlated quantitatively with burst integrated flux density. One of the events was visible in white light and also had an associated ground level event. The spectra of the largest bursts are considered. As early as 31 July 1972, many unusual bursts at wavelengths shorter than 3 cm were observed as point brightenings with excellent x-ray association. Though discussions are at times presented, the emphasis of this report is on presentation of data. (Modified author abstract).

Book Synopsis Forecasting Peak Proton Flux and PCA Event Magnitudes Using 'flash-phase' Integrated Radio-burst Flux Density by : David T. Newell
Download or read book Forecasting Peak Proton Flux and PCA Event Magnitudes Using 'flash-phase' Integrated Radio-burst Flux Density written by David T. Newell and published by . This book was released on 1972 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new parameter is introduced for use in forecasting the magnitudes of solar proton and polar cap absorption events. Semi-integrated flux density is the integrated radio flux density under the start-to-maximum burst curve. An approximation to this function was correlated at five operational frequencies against both observed peak proton flux and observed riometer absorption, obtaining correlation coefficients > or = 0.88 at frequencies between 2695- and 8800-MHz. An operational real-time forecast scheme is detailed for the solar forecaster. Results from this study, which uses peak proton fluxes both corrected and uncorrected for solar disk positions, indicate that forecasts have a higher degree of correlation with observations if propagation corrections are not applied as present methods dictate. When used in conjunction with the Castelli 'U' burst spectrum criteria for forecasting the occurrence of proton events, radio data can be used exclusively for both a yes/no and an event magnitude forecast. A comparison with the method presently in use at the Air Weather Service's Aerospace Environmental Support Center, Solar Forecast Branch is made with very favorable results. (Author)

This book was released on 2012-12-06 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: K. O. KIEPENHEUER ( Fraunhofer Institut, Freiburg i. Br., Germany) The present symposium, to my knowledge the largest ever held in the field of solar research (170 astronomers from 21 countries) was held in the building of the Hun garian Academy of Sciences in Budapest from September 4 to 8, 1967. It was the 35th symposium organized and sponsored by the International Astronomical Union. The majority of participants were financedfrom national sources. The Organizing Commit tee consisted of K. O. Kiepenheuer (Chairman), L. Davis, L. Dezso (Local Organizer), A.D. Fokker, R. Michard, A.B. Severny, H.J. Smith, Z. Svestka, and H. Tanaka. In order to ensure prompt publication, the manuscripts had to be supplied by the authors 1 month after the meeting. The discussions have been recorded on tape. Their reproduction in this book, however, is based almost completely on the contributors' writing down their comments and questions on the spot. Two special projects have been reported and discussed shortly during the sym posium: The world wide project 'Cooperative Study of Solar Active Regions' (CSSAR) organized by Dr. R. Michard, under the auspices of the IAU, which has put at the disposal of our solar community a precious observing material on Active Regions over a period of 6 months.
