摘要:

In January 1959 theJournal of Geophysical Researchpublished a paper by R. T. Hansen citing my paper. An explanation of the terminology and of why my results are opposite to those of Hansen is necessary. Hansen mentions the connection between quiescent prominences and geomagnetic storms, and by comparing the character figures for dark Hα flocculi from 1917 to 1944 he shows that no such connection exists.On the other hand, from my work a certain connection between recurrent geomagnetic storms and one kind of filament‐prominences, which I have called free filaments, clearly does exist. These filaments, however, are in no respects identical to quiescent prominences as they are usually defined in the literature. Moreover, they are not to be identified with all the formations included in the character figures used by Hans

摘要:

In connection with the IGY program, Aerobee rockets were launched at Fort Churchill, Canada. For the purpose of obtaining wind and temperature data at high altitudes, grenades were fired from these rockets. At the firing of the Aerobee SM 105 on August 19, 1957, the positions of the grenade bursts were recorded by a photogrammetric camera system consisting of Wild BC‐4 instruments. In addition, smoke puffs from the grenade bursts were illuminated by the sunlight, and the drifting trails could be identified on the photograph

摘要:

The profile of the Lyman‐α line of hydrogen in the radiation from the sun was determined using a photographic spectrograph, flown in an Aerobee‐High rocket on July 21, 1959, as a part of the United States effort in the International Geophysical Cooperation, 1959. The instrument employed a 50‐cm radius, 1200 I/mm diffraction grating in the 13th order, following a design originated by Dr. Robert J. Meltzer of the Bausch and Lomb Optical Company. Overlapping orders and stray light were effectively eliminated by means of a similar grating as a predisperser; this grating was used at an angle of incidence such that the optical system as a whole was stigmatic. Therefore, points along the spectrum line corresponded to points in a narrow slice diametrically across t
