We have explored two automated classification methods: supervised classification using Artificial Neural Networks (ANN) and unsupervised classification using Self Organized Maps (SOM). These methods are used to classify IUE low-dispersion spectra of normal stars with spectral types ranging from O3 to G5. This paper describes the application of automated methods to the problem of the classification of stellar spectra. ...

... Low-latitude aurorae are a storm time phenomena, in which particles originating from the ring current (and/or which are energized by the ring current) enter the lower thermosphere causing optical emission. It has been suggested (Rassoul et al., 1993) that four "pure" types of such auroras exist, as shown in table below, where LEE = low energy electron aurora, and HP = heavy particle aurora. ... low-latitude . ...
