    Notes: [Auszug] Both the Ap and vorticity area index exhibit annual variations and long term trends. The annual variations and long term trends were removed from both data sets and the resultant series normalised so that the average of each index is zero. We have calculated least-squares estimates of the Fourier ...

    Notes: [Auszug] Gnevyshev and Novikova10 refer to the work of several other groups, published in Russian and unavailable to us. Seventeen papers are referenced, all of which are said to suggest the possibility of direct effects of solar activity on living organisms. They present evidence of two types: first, the ...

    Notes: Abstract The physical mechanisms associated with solar flares are reviewed. The relevance of flare mechanisms to other astrophysical phenomena is discussed. In this context, specific models of quasars and radio galaxies, Sco X-1 and gamma-ray bursts are examined.

    Notes: Abstract A simple model facilitates calculation of the influence of magnetic field configuration on the conduction cooling rate of a hot post-flare coronal plasma. The magnetic field is taken to be that produced by a line dipole or point dipole at an arbitrary depth below the chromosphere. For the high temperatures (T ≳ 107 K) produced by flares, the plasma may remain static and isobaric. The influence of the field is such as to increase the heat flux (per unit area) into the chromosphere, but to decrease the total conduction cooling of the flare plasma. This leads to a significant enhancement of the total energy radiated by the flare plasma.

    Notes: Abstract This report summarizes the proceedings of a meeting held on 17–20 September 1974, at Stanford University. The purpose was to explore plasma physics problems which arise in the study of solar physics. Sessions were concerned with specific questions including the following: Is the solar plasma thermal or non-thermal? What spectroscopic data are required? What types of magnetic field structures exist? Do MHD instabilities occur? Do resistive or non-MHD instabilities occur? What mechanisms of particle acceleration have been proposed? What information do we have concerning shock waves? Very few questions were answered categorically but, for each question, there was discussion concerning the observational evidence, theoretical analyses, and existing or potential laboratory and numerical experiments.

    Notes: Abstract A workshop, held at Stanford University on August 29 and 30, 1974, brought together two groups of scientists interested in extraterrestrial civilization (ETC). Group A is comprised of scientists studying the problem theoretically in terms of physical, astronomical and biological knowledge, and those considering searching for extraterrestrial radio signals which might provide evidence for ETC. Group B comprises scientists pursuing the UFO problem their activities comprise analysis of soft evidence such as eye-witness reports, and of hard evidence such as photographs. Discussion at the Workshop centered on the following topics: the existence of ETC; interstellar travel; interstellar communication; human contact with ETC; UFO evidence; evaluation of the UFO phenomenon; and assessment of our ignorance. It was generally agreed that radio search for ETC is a promising endeavor. Althought it was agreed that study of the UFO problem is a justifiable pursuit, members of Group A chose to remain skeptical in the absence of unimpeachable evidence concerning the nature of the phenomenon.
