Today itâs considered one of the worldâs leading observatories. Yet thereâs little coordination between even the best observatories in the United States.

Asterixis (also called the flapping tremor, or liver flap) is a tremor of the hand when the wrist is extended, sometimes said to resemble a bird flapping its wings. This motor disorder is characterized by an inability to actively maintain a position, which is demonstrated by jerking movements of the outstretched hands when bent upward at the wrist.
