Zur Korrelation zwischen dem Auftreten von Kometenschweifen des Typ I und der solaren Korpuskularstrahlung

For 52 comets the correlation between type I‐activity and the latitude of perihelion is studied. In the interval −30° ≦ β ≦ + 30°, 70% of the comets show a type I‐tail. At greater latitudes the appearance of such tails decreases perceptibly. If the formation of type I‐tails is caused by the solar corpuscular radiation as assumed by B IERMANN , then one may conclude that the dispersion of the solar particles is restricted to the latitude interval under consideration up to a distance of at least 0.5 A. U. (the mean perihelion distance of the comets investigated).
