CATALOGUE OF HUET AURORAL SPECTRA 1957-1963,
ALASKA UNIV COLLEGE GEOPHYSICAL INST
Pagination or Media Count:
The zenith auroral spectra at College, Alaska, obtained during the six observing seasons from the fall of 1957 through the spring of 1963 were assembled into catalogue form. From the general appearance of the spectra and other factors a table of daily activity index numbers 1-9 is given for each observing period. The monthly averages of these index numbers were plotted for this entire period and compared with various indices of solar and geomagnetic activity. An anomalous increase in the auroral activity index in the fall of 1962 destroys an otherwise perfect trend in the relation of the auroral activity to the decline in the sunspot cycle. Author
