Surprise discovery of new Southern Hemisphere meteor shower

25 February 2016 Astronomy Now

The shower is called the Volantids, named after the constellation Volans, the flying fish, from which the meteoroids appear to stream towards us. The shower was not seen the year before and is not known from past radar observations. It could be an early warning that we should be looking for a potentially hazardous comet in that orbit.
