AIRK

They come from constellation Ophiuchus, near Yed Prior.

Considered by other races as peaceful.

The purpose of their visits is unknown...they never stay long on Earth and do not interact with Humans or other aliens here.

They mostly use Earth as a "stop" (to quickly gather something they may need) before they leave to their real destination.

They are mostly nocturnal.

Their ships emit a bright-orange light and are (most of them, not all) octogonal in shape.

Last spotted near London (England) in May 2003.
