Abstract
To summarize, we find that the radiotechnique of meteor observation enables us to extendthe systematic recording of meteor rates down to the9th or 10th magnitude; to determine satisfactoryheights and velocities on a scale previously impossible;to calculate the orbits of meteor showers and individual meteors, in particular those that appear onlyin the daytime; and to study wind drift and finestructure in the ionosphere. The radio observationshave quite definitely indicated that down to the 9thmagnitude, corresponding to particles approximately1 mm in diameter, meteors are members of the solarsystem and do not come from interstellar space.
