Steve is an important discovery because of its location in the sub auroral zone, an area of lower latitude than where most auroras appear that is not well researched. (sciencedaily.com)
Recently, Hallinan et al. (2015) reported simultaneous radio and optical spectroscopic observations (obtained with the Karl G. Jansky Very Large Array (VLA) radio telescope and the Double Spectrograph (DBSP) on the 5.1 - m Hale telescope, respectively) of auroral emissions of an object at the end of the stellar main sequence (i.e. at the boundary between stars and brown dwarfs).

There, the charged particles strike molecules in Earth's atmosphere that release photons of various colors (red hues come from oxygen, for example) and light up polar regions in frequent auroral displays. (scientificamerican.com)
