Hourly distribution of AS-impulses. 



This same distribution we lind again in the case of the 6^-storms, 

 but much more pronounced; a principal maximum at about S^^ a. m., 

 and a secondary one at 6^' p. m. 



Accordingly the hour of commencement of the (r-disturbances is 

 dependent upon the position of the station with respect to the sun, 

 and it seems, that the hours most appropriate for the development 

 of a (r-disturbance also favour the development of an >S-im pulse.
