 note = {The routine observation of VLF emissions was begun at Moshiri in January last year, using crossed loop antennas of triangle type of 2 turns, 43 meters in hight and 60 meters at the base. The observing frequency range is from 4 kc/s to 6 kc/s. The recording system used is the minimum reading pen-recorder, developed by G. R. A. Ellis. The results obtained from the observation during the period from January to November 1963 indicate that the VLF emissions are observable at geomanetic latitudes as low as 34° and the majority of the VLF emissions are of hiss type, but during severe magnetic storms chorus are also observable and that the correlation between occurrence rate of noise burst and geomagnetic activity, measured by daily k-index and magnetic storm, is very close, however, it does not seem so close with the pt type geomagnetic pulsation, while the peak flux density of noise burst does not appear to depend directly on geomagnetic activity. In order to confirm these results a more detailed investigation with a full data of geomagnetism and considerations on effects of atmospherics may be needed.},
