Despliegues aurorales observados desde la Estación Belgrano
Main Article Content
Abstract
Our research was based on different kinds of auroral observatons at Belgrano Station (78.0°s, 38.8°w). we have studied 145 dark days, from March to September, 1971.
We have obtained about 45% nights without identified auroral displays, because periods with bright moonlight and bizzards were rejected.
Sudden enhancement of emissions occurred about 41.4%, 37.5% and 21% (for the lines of 557.7nm, 630.0 nm and 427.8nm, respectively) of the identified events. during July, August and September we have seen the increases of sudden enhancement of atomic oxygen emissions and the corresponding decreases of the nitrogen bands.
The annual period of auroras observed at Belgrano Station, shows a peak at the time of the spring-equinoxe, and they are most frequent around the local midnight with a maximumat around the 3 hs (Universal Time).
