Title: Joint solar dynamics project data summary (2nd): solar magnetic field, chromospheric and coronal observations near the time of the 11 June 1983 solar eclipse. Technical note

Abstract

A comprehensive set of observations of the solar photosphere, chromosphere and corona is presented for one week on either side of the 11 June 1983 total solar eclipse. These observations, made at the Mauna Loa Solar Observatory and at the University of Hawaii's Mees Solar Observatory on Haleakala, include H images of the disk and the limb, off-band H sunspot and Ca-II K-line images, together with observations of the white light corona. Also included are photospheric longitudinal magnetic field estimates made from the Fe line at 6302.5, by the Mees observatory Stokes photo-polarimeter. The data are presented as daily observations. In the case of the k-coronal observations and the magnetic field data, synoptic maps have been constructed for this interval.

  • The general goal of the HAO/University of Hawaii Joint Solar Dynamics Project is to establish the relationships that exist between the solar magnetic field, detected in the photosphere, and the structure and evolution of the corona. The SOLDYN programs of 1982 and 1983 demonstrated the ability to use existing instruments to gather data of value in the pursuit of that goal. The goals for the observations in 1988 are as follows: (1) document the state of the sun, from the photosphere up through the chromosphere and out into the corona for the approximately four-week interval around the total solar eclipsemore » of 18 March 1988, and (2) identify the relationship between the photospheric magnetic fields and the temperature and density structure of the corona. This report contains the reduced observations made during this SOLDYN III period necessary to achieve these goals. They are presented both in the form of daily photographic and photoelectric measurements, and in synoptic format for the period.« less
  • Photospheric, chromospheric and coronal data were collected by the Mees Solar Observatory (University of Hawaii) and the Mauna Loa Solar Observatory (NCAR) over the period 14 June - 13 August 1982. These data are presented in a 2-page-per-day format with four solar images (H(alpha), CaII, H(alpha)Limb, and Sunspot) and four coronal contour maps. A listing of data coverage for this period is provided in the text as well as a summary of solar activity detected during this period.
  • Observations made during the interval March 1-31, 1988, are presented which were designed to provide a synoptic context in which data from the March 18, 1988, total solar eclipse can be interpreted. Daily observations made with the Mark III K-coronameter and the H-alpha prominence monitor at the Mauna Loa Solar Observatory, along with photographic records of the Sun in H-alpha from the flare patrol at Mees Solar Observatory on Haleakala, Maui, are included. Observations of the longitudinal component of the photospheric magnetic field made at Mees Solar Observatory were also gathered around the period of the eclipse. Together with themore » white-light image of the corona at the eclipse, these coronal and magnetic field observations assembled into synoptic maps for this epoch, are presented. On the basis of these observations, an interpretation of the global density distribution of the corona at the time of the eclipse is constructed. 11 references.« less
  • Daily magnetogram observations of the large-scale photospheric magnetic field have been made at the John M. Wilcox Solar Observatory at Stanford since May of 1976. These measurements provide a homogeneous record of the changing solar field through most of Solar Cycle 21. Using the photospheric data, the configuration of the coronal and heliospheric fields can be calculated using a Potential Field -- Source Surface model. This provides a 3-dimensional picture of the heliospheric field-evolution during the solar cycle. In this report the authors present the complete set of synoptic charts of the measured photospheric magnetic field, the computed field atmore » the source surface, and the coefficients of the multipole expansion of the coronal field. The general underlying structure of the solar and heliospheric fields, which determine the environment for solar - terrestrial relations and provide the context within which solar-activity-related events occur, can be approximated from these data.« less
  • Using observations of both hard x-rays and gamma-rays in the large solar flare on June 7, 1980, we infer the amount of chromospheric heating due to bombardment both by non-thermal electrons and by protons, respectively. If a thick-target model for the X-ray bremsstrahlung is adopted, then proton heating is shown to be important only in the lower chromosphere; however, if the hard X-rays are substantially thermal in origin, then proton heating may play an important or indeed dominant role in determining the structure of the entire flaring chromosphere.
