Haritath was a Human colonist on Tau Cygna V in 2366. Like the other colonists, he was immune to hyperonic radiation, and was a close friend of Kentor.

When Lieutenant Commander Data arrived to arrange the evacuation of the colony due to the demands of the Sheliak, Haritath was the first to greet him. He was convinced along with Kentor of the need to evacuate, but did not say so openly until the colony's leader, Gosheven, was himself convinced. (TNG: "The Ensigns of Command")
