 note = {As part of the Study Program of I. G. Y., we have prepared an observation of whistling atmospherics. Since Jan. 1956, continuous observations of whistlers have been made at Toyokawa (geomagnetic latitude 24.5°). Simultaneous observations at Toyokawa and Wakkanai (geomagnetic latitude 35.3°) were made for one month beginning 13 July 1956. The results obtained in the analysis of the dispersion of whistlers were essentially similar to those reported by Storey. But, at Toyokawa, long whistlers, whistler trains and whistler pairs have not been observed, only short whistlers being observed. The greater part of the observed whistlers occurred in winter; in other seasons it was scarcely possible to detect them. At Wakkanai, long whistlers and whistler pairs have been observed this summer, but whistler trains have not been observed during this period.},
