On the topology of filaments and chromospheric fibrils near sunspots
The similarity between the spiral topology of chromospheric fibrils and filaments observed in Hα near sunspots and the configuration of an axisymmetric force-free magnetic field is examined. It isExpand

EVIDENCE OF CLOSED FLUX LOOPS IN THE SOLAR ATMOSPHERE
Since March 1956, the observers at Climax, Colorado, have included in their routine observations of the sun the photography of the spectrum of the Ha line and vicinity at all points around and at aExpand

Spectroscopic Limitation on Coronal Heating Mechanisms.
Spectroscopic observations of the corona have implications concerning its heating mechanism. Specifically, the very small amount of gross Doppler shifts in coronal lines limits severely the types ofExpand

Dynamical implications of Si iv line profiles from OSO-8 observations
The widths and rms variations of line centers for λ1393 profiles from the Si iv ion in the solar transition zone, as observed by OSO-8, are analyzed to give the amplitudes and periods of threeExpand

Emission in Hydrogen Balmer Lines and Continuum in Flash Spectrum of 1952 Total Solar Eclipse at Khartoum, Sudan.
Analysis of the spectrograms of the chromospheric flash obtained at the 1952 solar eclipse in Khartoum, Sudan, presented serious photometric problems. Standardizing exposures made at Khartoum wereExpand
