On June 30, 1973, Concorde 001 intercepted the path of a solar eclipse over North Africa, Flying at Mach 2.05 the aircraft provided seven observers from France, Britain and the United States with 74 min of totality bounded by extended second (7 min) and third (12 min) contacts. The former permitted searches for time variations of much longer period than previously possible and the latter provided an opportunity for chromospheric observations of improved height resolution. The altitude, which…

Visual Determination of the Mean Effective Chromospheric Thickness
IN the course of taking submillimetre chromospheric data from Concorde 001 during the eclipse of June 30 (ref. 1), it proved possible to record information on the visual thickness of the chromosphere
Submillimetre brightness spike at the solar limb
WE report here the first complete phase of the reduction of data obtained during the solar eclipse of June 30, 1973 from the high altitude moving platform provided by Concorde 001. Reports of the
Solar eclipses as an astrophysical laboratory
A new generation of ground-based eclipse observations reaches spatial, temporal and spectral-resolution domains that are inaccessible from space and therefore complement satellite studies.
Interplanetary shock waves: Recent developments
Direct and indirect observations of interplanetary shock waves have been extended to the study of (i) the shock structure itself; (ii) the disturbed solar wind in its wake; (iii) additional
A New Facility for Airborne Solar Astronomy: NASA’s WB-57 at the 2017 Total Solar Eclipse
This paper used the 2017 Aug 21 eclipse as a pathfinding mission for high-altitude airborne solar astronomy, using the existing high-speed visible-light and near-/mid-wave infrared imaging suite mounted in the WB-57 nose cone, and preliminary analysis of data quality from the existing instrument suite.
Solar-Terrestrial Relations and Magnetospheric Substorms
In studying solar-terrestrial relationships, it is important to recognize first of all that there is the basic solar-interplanetary magnetic field structure which has been revealed by two important
Chasing White-Light Flares
In this memoir I describe my life in research, mostly in the area of solar physics. The recurring theme is “white-light flares,” and several sections of this paper deal with this and related

    Living reviews in solar physics
  • 2014
Several avenues of solar physics research exploiting and benefiting from observations at infrared wavelengths from roughly 1000 nm to 12 400 nm are discussed, and the instrument and detector technology driving this research is briefly summarized.
Fourier spectroscopy in planetary research
The application of Fourier Transform Spectroscopy (FTS) to planetary research is reviewed. The survey includes FTS observations of the Sun, all the planets except Uranus and Pluto, the Galilean
Numerical modelling of shock waves in the solar wind
This review briefly surveys some recent progress in the numerical simulation study of magnetohydrodynamic (MHD) shock waves in the solar wind.
