Absorption Measurements During the Solar Eclipse of July 20, 1963


Book Description

Riometer data obtained from several Canadian stations during the total solar eclipse of July 20, 1963, are presented and discussed. A small increase in cosmic noise level, amounting to about 0.25 dB at 30 Mc/s, was observed at Ottawa, Cape Jones, and Churchill. (Author).







Observations of Ionospheric Behavior During the Solar Eclipse of 20 July 1963 at Bedford, Massachusetts


Book Description

Observations of the ionosphere during the 20 July 1963 solar eclipse at Bedford, Massachusetts are presented. A C-4 vertical incidence sounder was used. Critical frequencies and virtual heights of the ionosphere are plotted and compared with a 10-day average curve. Ionograms of the time of first contact, maximum eclipse and fourth contact are included. A series of optical photographs of the sun in eclipse, taken at ground level, are presented. (Author).




Radio Observations of the Solar Eclipse of July 20, 1963 at 74 Mc./s


Book Description

The residual solar flux density during the maximum phase of the July 20, 1963 eclipse was found to be 52%=5% at 74 Mc./s. The quiet sun flux density was estimated to be 1.0 X 10 to the minus 22nd power =7% w./m squared/c.p.s. (Author).







Solar Radiation at 3.2 Mm During the 20 July 1963 Eclipse


Book Description

The investigation of 3.2 mm solar emission during the 20 July 1963 solar eclipse is described. While the measurements were restricted by inclement weather, the observations by circularly scanning the limbs of the moon over a period of =10 minutes of the maximum occultation showed strong radiation from southeastern and southwestern limb prominences and no systematic limb brightening for the solar conditions at the time of the eclipse.
